I can't say they do.
But their may be a possiblity of it,
As because of the greatest clue called "Wow! signal"
Wow! signal was picked by the Big ear radio was a strong narrow band radio signal detected by Jerry R. Ehman of 15 August 1977.It was '6EQUJ5' frequency.
It was the a unique signal which was conclude to be a alien signal or a extra-terrastiel region.but it was never ever detected further by any scientfic radio station.
Wow! signal is had been the greater belive of any alien live present in the univers.
We will need more than high-tech hardware to find an answer. In many ways it is a spiritual question. In groping for an answer, man reveals some of his most cherished hopes: the end of war, the end of disease, perhaps even the attaining of immortality itself. So the stakes are high. But after centuries of wondering and decades of searching, how close is man to an answer?
The New York Times reports: “The search for intelligent life elsewhere in the universe . . . began 25 years ago . . . The awesome task, which involves scanning hundreds of billions of stars, has so far yielded no clear evidence that life exists beyond Earth.”—July 2, 1984, p. A1.
The Encyclopedia Americana says: “No other planets [outside our solar system] have definitely been detected. But for each planet that might exist outside the solar system, there is a chance that life began and evolved into an advanced civilization.” (1977, Vol. 22, p. 176) (As reflected in this statement, could it be that a major motivation in the extremely costly search for life in outer space is the desire to find some proof for the theory of evolution, some evidence that man was not created by God and so is not accountable to Him?) Revelation 4:11.
The Bible reveals that life on this earth is not the only life there is. There are spirit beings—God and the angels—that are vastly superior to man in intelligence and power. Psalm 104:4 They have already communicated with humankind, explaining the origin of life and what the solution is to the overwhelming problems that confront the world.
