If we were talking about anything else (secret government programs, etc.) I would completely agree with you.
But there is no such thing as life on another planet. Thousands of sci-fi movies and books notwithstanding.
It doesn't matter how many Media companies declare Biden the winner; it doesn't make it true. Likewise, even if everyone on earth collectively agreed that aliens exist, it wouldn't bring them into being :)
I don't think there is either --- life is too complicated to have emerged by chance, it requires just the right conditions, Almighty God
could have created life (in any form) on another planet with the same or very similar conditions, but why would He have?
I suppose in 100 years, everyone on this forum will know one way or the other --- that is, if God chooses to reveal this to us in the next life. If it is a theological truth that created souls will have knowledge equal to what the Godhead has, that would come as news to me. Even if He created it, He does not have to tell us one way or the other.
I said "next life". If we end up in Heaven, we may know or we may not. If we end up in Hell, the existence of extraterrestrial, temporal life will be the least of anyone's concerns. Much more pressing matters, front and center, for all eternity.
