Hello @mohajer
I do not know that there are creatures other than humans in this vast universe, but we can not be sure of that.
That's right!
As for the religions are eternal existence and will not disappear, perhaps some people change their religion because of the evidence that he found and convince him that this religion is the right religion.
Those whose belief is not strong will fall. And also those whose belief is too rigid will fall.
And that life will be destroyed as agreed upon in all religions
That's material for another post.
Thanks for coming by
