It might be worth unpacking the question about whether there is life elsewhere in the universe because BeRational's position here is extremely useful in showing the position of quite a number of the atheists on this board. When he states that he does not believe in life elsewhere in the universe, he is not taking the position that there is no life elsewhere in the universe.
Taking the hypothetical of there actually being life found in meteorites, if that had happened but BeRational had not heard of it, his position based on the evidence to hand is still logical. If there are claims of such life being found, and he is aware of them, then until those claims are investigated, his position is still logical.
