OK, then where did all matter come from? Something is eternal, either matter or God...and the thought that it's matter is irrational. Or will you resort to the last explanation I got from an evolutionist and claim matter popped into our dimension from an alternative one...which is no answer but simply a displacement of the inability to answer the question.
If matter from another universe popped into this one, you’re right. One then has to ask where the other universe came from. You task would be to explain where God came from.
