Holy fucking shit, buddy:
"where did the universe come from?"
It didn't "come from" any anywhere.
Zeus didn't shit it out his ass.
The universe, just like 2+2 = 4 has always existed. As in ALWAYS, forever, without end.
Tough concept for you.
Think about it buddy.
Chocolate ice cream was created for the first time, not by some Hoodoo God, but by a human.
The internet, ditto.
Electric light bulbs, ditto.
The universe needed no supernatural imaginary being: God, Yahweh, Zeus, the Flying Spaghetti monster.
It's just always been here. Just like 2+2=4.
So what do you religio freaks think - did God sit down one day and ask himself:
Hmmm should I make 2+2=4, or 2+2=3?
