God didn't begin to exist without cause. The premiss is that everything that BEGINS to exist has a cause for its existence.
God's begininglessness is not assumed by the argument, it is established by it.
Examples of things that begin to exist without cause, please...(not God as established by my arguments)...under your view, this should happen all the time.
The universe can't be infinite in the past because an infinite regress of cause and effect is an actually infinite set of events. Any mathemetician knows that an actually infinite set of anything is impossible. Therefore an eternal universe is impossible. This is not speculation.
Time and matter came into existence at the same moment. Consult Einstein.
I already told you about an impersonal set of mechanical causes. Are you seriously talking about a personal set of mechanical causes?? Read my arguments carefully.
You have done nothing to show that my premisses are faulty.
