This is all part of an new openness policy  adopted by the United Nations in February 2008.
The Vatican has willingly participated in this by openly presenting a theological position that extraterrestrials “are our brothers,” as they sponsored an astrobiology conference which made public discussions on the existence of extraterrestrial life.  Rejecting the hostile portrayal of extraterrestrials in Hollywood movies, the Vatican has adopted an active role in preparing people for some kind of disclosure of extraterrestrial life that many believe is inevitable. I guess they do not want to repeat their mistake they did with Galileo.

Back in November 2009, The Vatican completed a five day conference where scientists convened to discuss the detection and implications of extraterrestrial life. The conference itself was officially convened by the Vatican's Pontifical Academy of Sciences, chaired by its religious leader Bishop Marcelo Sanchez Sorondo held on Vatican grounds. The Vatican’s openness to discussion of extraterrestrial life is no accident.  The conference primarily focused on the detection of primitive extraterrestrial life forms, and featured presentations from nearly 30 international experts in astronomy, physics and biology.

Prof Paul Davies commented on the religious implications of discovering intelligent extraterrestrial life: "If you look back at the history of Christian debate on this, it divides into two camps. There are those that believe that it is human destiny to bring salvation to the aliens, and those who believe in multiple incarnations," Davies pointed out that the multiple incarnations theory, the idea that multiple examples of Jesus Christ would be found in the universe “is a heresy in Catholicism."

A major driving force behind the conference was the Director of the Vatican Observatory, Jesuit priest Father Jose Gabriel Funes an Argentine named to his position by Pope Benedict XVI in 2006. In May 2008, Funes gave an interview to the Vatican’s L’Osservatore Romano newspaper saying that the existence of intelligent extraterrestrials posed no problems to Catholic theology.

Father Funes said it was difficult to exclude the possibility that other intelligent life exists in the universe, and he noted that one field of astronomy is now actively seeking "biomarkers" in spectrum analysis of other stars and planets.

These potential forms of life could include those that have no need of oxygen or hydrogen, he said. Just as God created multiple forms of life on earth, he said, there may be diverse forms throughout the universe. "This is not in contrast with the faith, because we cannot place limits on the creative freedom of God," he said. "To use St. Francis' words, if we consider earthly creatures as 'brothers' and 'sisters,' why can't we also speak of an 'extraterrestrial brother?'" he said.

Asked about implications that the discovery of alien life might pose for Christian redemption, Father Funes cited the Gospel parable of the shepherd who left his flock of 99 sheep in order to search for the one that was lost.

"We who belong to the human race could really be that lost sheep, the sinners who need a pastor," he said.

As an astronomer, I can say that from the observation of stars and galaxies there emerges a clear evolutionary process," he said.

He said that in his opinion the big-bang theory remains the best explanation of the origin of the universe from a scientific point of view. Above all, it's a reasonable explanation, he said.

Father Funes said that Christ's incarnation and sacrifice was a unique and unrepeatable event. But he said he was sure that, if needed, God's mercy would be offered to aliens, as it was to humans.
"God became man in Jesus in order to save us. So if there are also other intelligent beings, it's not a given that they need redemption. They might have remained in full friendship with their creator," he said.

As for the biblical account of creation, Father Funes said it was wrong to expect a scientific explanation from the Bible.

Recently the Pope has repeated this sentiment, as he is willing to baptise aliens. Pope Francis on Monday declared that everyone has the right to be baptised, even aliens should they come knocking on the church’s door.

Christians cannot “close the door” to all those who seek baptism even if they are “green men, with a long nose and big ears, like children draw,” the pope said at his daily mass, according to Vatican Radio. May 13 2014)

This Pope is so inclusive that he says he would baptize aliens to become members of the Catholic church. “If, for example, tomorrow an expedition of Martians came to us here and one said ‘I want to be baptised!’, what would happen?” Who are we to close doors?”

This statement is pretty meaningless as aliens are not descended from Adam; they are not born with sin (this is what the baptism is alluding to in Catholicism, original sin being washed away). The angels that sinned do not have a way to be redeemed because  of their greater accountability, as they were in heaven before God's presence.

This is opening up nearly a billion Catholics to the deception of alien life. But what of the so called aliens tell them they have a religious system superior?

According to the director of the United Nations Office for Outer Space Affairs We Earthlings are poorly prepared to respond should there be contact from aliens,  “Statistically, extraterrestrial life is a possibility,” some say we are going to need to expand our idea of religion. NASA claims alien life WILL be discovered in the next 20 years.

US SPACE agency experts say there are thousands of planets in the universe that could host life. "Astronomers think it is very likely that every single star in our Milky Way galaxy has at least one planet." NASA has already discovered more than 5,000 planets that could sustain life and many more could still be found.

NASA's Kepler mission  found 715 new planets outside our solar system. Everyone's excited, https://www.rant-lifestyle.com/2014/02/27/15-mind-blowing-facts-new-planets-nasa-found-scientists/

They want to determine if the planets are the right distance away from the star to have liquid water - the key ingredient to life as we know it. This all is connected and supports an alternate explanation of how we came to be, using the evolutionary theory as the basis.

The key ingredient is God, He is the one who gives life. But the scientists think the only thing more intelligent than man is alien life (they can't be inferior?)

In 1967 British astronomer Jocelyn Bell Burnell discovered mysterious pulsing signals coming from outside the solar system. For months she suggested the signals could be of an extraterrestrial intelligent origin, but they were later proven to be rapidly spinning stars known as pulsars.

Are mystery radio bursts messages from ALIENS? A new series of mysterious signals are making scientists wonder if we’re picking up alien messages. Scientists are trying to work out what is causing Fast Radio Bursts (FRBs). First being detected in 2007 by astronomer Duncan Lorimer and his team. Only a handful have been seen and the explanations range from colliding neutron stars to alien signals. Images show the dispersed signal from the original millisecond radio burst that suggests it must have originated billions of light-years away.

Here is where we can be led on a rabbit trail by intelligences that are more devious then scientists anticipate. After all, WHAT ELSE COULD THE SIGNALS BE?

Archbishop of Washington, Cardinal Theodore Edgar McCarrick, told reporters at the National Press Club, a contemporary Catholic "need not say that creationism is the only answer -- that in six days or seven days, God made the world," according to the Associated Press.

Creationism is the literal, biblical account of God creating man and the universe in six days. McCarrick said this concept of "theistic evolution" – agreeing with Darwin's evolutionary theory, given that one accepts God’s guidance in the process -- was the view of the late Pope John Paul II.

Henry Morris writes

Perhaps the most influential evolutionist among Catholic theologians was the Jesuit priest, Teilhard de Chardin, now considered in effect to be almost the "patron saint" of the New Age movement with his strong pantheistic evolutionism. Teilhard was involved in the controversial discoveries of both Piltdown Man and Peking Man, and vigorously promoted total evolutionism all his life, greatly influencing such leading secular evolutionists as Theodosius Dobzhansky, George Gaylord Simpson, and Sir Julian Huxley. His books were banned at one time by the Catholic church but have apparently become respectable, and even very influential among Catholics during the reigns of the recent more liberal popes.” http://www.icr.org/article/evolution-pope/

Are we going to hear an announcement on UFOs and extraterrestrial life? As we continue to unite to fight the threat of worldwide terrorism we are becoming a global society, will it go beyond this? Are we going to welcome the unearthly beings as friendly or will mankind have to unite against a more common enemy, a false threat of aliens.

The UFO’s speak of a new world coming. Could one of many false messiah’s be an alien? The main chess game is to overthrow believers. If we accept alien life elsewhere, as evolution teaches the truth of the bible is negated and any explanation can fill the void.

Imagine if a UFO landed and someone comes out dressed in a white robe saying he is Christ. How much would this change our worldview? What would the world say? What would the church say, after all Christ came back just as he left, (Acts1:11) from the sky, and every eye beheld him. But its not Jesus. If this were to take place, it certainly would be the greatest deception ever fostered upon mankind. What if he had powers and was able to do signs or miracles, how could anyone refute this! This isn’t speculation, as channeled messages from these space brothers and spirits are saying this.

What if they endorsed a certain belief, or religion, or gave a new religion. How would we deal with it? Since they are far more intelligent than us we would assume they are right.

Maybe our thinking ahead on this is matter is an exercise of futility, or, maybe it is preparation for something we cannot fathom at the time.

There is no doubt that UFO’s, aliens will play a part in the end times deception. In fact this belief goes hand in hand just with evolution. Its really not that impossible to deceive the majority of mankind, as we have already taken a giant leap by believing in evolution. It makes sense that we are not alone to those who refuse the bibles revelation.
