Why does the Universe exist

suppose the big bang is true....

then WHY?!?!

if there was no omnipotent being that started the big bang....

WHY did it happen?

something from nothing?!?!?!

why did that little POINT of UNIMAGINABLE concentrated energy exist?

what if the universe has existed for eternity?

what if the universe is of INFINITE size?

HOW could it be INFINITE? WHAT if it has existed FOREVER?!! WHY? How could there NOT be an omnipotent omni-benevolent being/creature of SOME sort controlling everything?
