Somebody said this to me

This is the "uncaused cause" argument, though I've never seen it in quite this format before.

One of the main flaws is that the big bang theory does not state the universe at one point did not exist, it says that it existed as a singularity, so the universe doesn't need to be created, as it is already there.

The "logical" step from disembodied creator to judeo-christian god is another huge flaw. The only thing that this (flawed) logic alludes to is the existence of said disembodied creator, and there is no basis for giving it the properties of the judeo-christian god.

So in all, this argument is based on a (probably) faulty premise with a highly flawed jump to the judeo-christian god.
