If there is no #God, life and death are meaningless as they are without purpose or consequence. The how and the why are worthless pursuits.
It is impossible to accept this synopsis because to do so would mean that everything (the universe and all that it is) is for nothing. To believe that it evolved by mere chance, came from nothing, means nothing and is of no consequence, is too stretch logic to breaking point.
Everything that happens everywhere, whether it be the birth and destruction of stars or galaxies, or the way we and all living things live and die has purpose and meaning. To suggest then that the Cosmos from which life evolved is not imbued with the same meaning and purpose that is demonstrated in everything we see is to admit that logic itself is meaningless.
That makes even less sense than believing in God. If science is based on logic then science has nowhere to go since the Universe itself is apparently without logic.
