The absurdity of considering something worthless just because it's not eternal has already been answered in this thread.Why do atheists care what happens in this life, if nothing happens after it? Is there any real reason to do anything before you die if, after you die, none of it really matters (or does it)? Where do you find meaning in life, when it is so ephemeral?
Let me quote myself :
"So what ?
You're dating a woman. Do you consider your love with her pointless and worthless just because in two years you may or may not be still together ?
You're spending an afternoon with friends and are having a blast. Does it make your friendship worthless and pointless just because some day you may not be friend with them anymore ?
You're eating a delicious dinner. Is this the same as fast-fooding yourself in a crappy McDonald just because one hour later you'll no longer have the taste in mouth ? "
And anyway, worth of life doesn't make God more or less valid. In fact, it strongly hints that what push you to believe in God is not his supposed existence, but that you're frightened by what it would imply to have no god - once again, a good example of why religion exists, more because of human psyche than actual reality.
