The Kalam Cosmological argument.

[Deesse23]

Step 2: The Universe began to exist. 

How do you know?

This step is also proven by mathematical logic, has empirical confirmation in the Big Bang Theory etc.

Wrong
If the BBT is right the universe existed for all of time.

Step 3: Therefore, the Universe has a cause.

And that cause would be? ....i bet your particular version of christian god. Am i remotely correct in this assumption?

The conclusion logically follows from the preceding premises. Dr. Craig occasionally goes for a further step.

Craig is dishonest from the get go, and admitted to his motivated reasoning in a video.

Step 4: Therefore, an Eternal Creator of the Universe exists, that brought the Universe into existence from nothing.

And now YOU are being dishonest. This step is not part of eh Kalam, isnt it?
Does your creator begin to exist by the way? No? how do you know?
