Tell me about it. I still remember asking my dad what came before the universe when I was a kid and he said, "No, there was no before." When I inquired again he said "Time is a property of our universe. You can't have a before without it. There wasn't nothing, there wasn't a before. You are part of this universe and cannot exist without it. There's no curtain to look behind, this is it."

That realization made me feel pretty stupid and caused a minor existential crisis.
