Christoid Logic

[Mister Agenda]

He may not have presented it well, but his point is valid. 

If I allow that an eternally existing god is possible, then yes, I must allow that an eternally existing universe is also possible. If the evidence indicated that the universe has existed eternally, or back when we didn't have evidence one way or another on that question, your counter argument was fine. But, now that the evidence indicates that the universe has a beginning, that counter argument no longer holds.

This iteration of the universe had a beginning. Whether that was the beginning of everything depends on what that hot, dense speck energy was doing before it expanded. Did time begin then? If so, the universe has literally existed for all of time. Was there already time? Was that hot dense thing around forever until then? Was it the product of a previous version of the universe?

We know about when our universe of matter and energy in the forms we observe started. We don't know what the heck was going on before that, or even for sure if 'before' has any meaning in this context.
