Where did God come from? Nothing?
Who knows? But why not give the same skepticism to the idea of "there is no God"? All science is a building of knowledge begetting knowledge; and yet we discard the most basic idea of cause and effect.
Which is why I ask - where have you seen something come from nothing? And yet without skepticism, you think it's possible - the causeless effect - matter appearing - governed by laws that came from ...nowhere??
Parallel universes, endless expansion and contraction; all of these are greeted with a "hhmmm... that's an interesting hypothesis, it's possible...yes I like the idea." And this without a single shred or inkling of possibility.
And yet, bring up the idea of a creative mind? Oh, the skepticism - "that's impossible - you're a fool for accepting the idea of a fairy tale."
Everything in our experience points to effects having a cause. Why don't we extrapolate that out when it comes to origins?
