:God or no god, why is there something rather than nothing?
You don't know there is something rather than nothing, and more importantly you assume they are mutually exclusive. In a set called "everything", can "nothing" exist? Of course it can. "Everything includes everything, and "nothing" is a part of everything.
:Why do elements have properties?
So you can spout your nonsense, that's why. God thought about YOU when he made stuff, and just to make you think this way, he gave elements "properties."
By the way, what are "properties" in elements?
: Why does consciousness exist?
So this board can survive? This is the ONLY reason for this that I know.
:These are questions that I think about almost every day.
I masturbate. It involves much less stress than your cosmic nonsense and actually does some good.
