That seems like the general reply. That's why there HAS to be a creator, because everything needed a "something" to begin it.
"We don't know" does not mean "it must have been created". There are many possibilities that do not involve a creator, and maybe we haven't even considered wahtever is the real possibility yet.
And, of course, if everything needed a "something" to begin it, what began the Creator? I know, you're going to say everything
except the Crator needed a "something" to begin it, and you're not going to have any rational reason why you're inserting that exception.
