In summary the reflect Christian Creationist apologist agenda, and not legitimate science and math. All known causes for the beginnings in the nature of our physical existence have an adequate natural explanation. No unnatural explanations have been discovered.
Is that a question? Is that suppose to be an argument for atheism? I am not trying to be arrogant, it is just that I don't understand what am I suppose to answer.
science and math, simply NO. The question of whether our 'physical existence' is infinite and/or eternal is unknown,and definitely cannot be answered by assertions of outdated Christian apologetics.
Again nobody is claiming 100% certainty, sure the ultimate answer on whether the universe had a beginning or not is "we don't know"
But the evidence strongly suggests that the universe had a begining.
1- a "past eternal universe" can not be an expanding universe (according to the bgv theorem) , but apparently we live in an expanding universe.
2 a past eternal universe would have an entropy of nearly 100% but apparently we live in a universe with low entropy
3 a past eternal universe would be dominated by Boltzmann brains, implying that you would be a Boltzmann brain and that the universe that you observe is an illusion..... But presumably you are not a Boltzmann brain. *
You claimed that your sources deal with this objection, please quote the relevant e
sentences
4 a past eternal universe would imply that an actual infinite amount if seconds a d events have occured ..... But I would argue that an actual infinite is logically absurd.... For example how did you go from
-infinity to
-13B years ago (the big bang)
None of these points represents an absolute proof, but the do represent good arguments for a begining. And I don't think you can provide comparably good arguments for an eferete universe
The good news is that each point is aplicable to a wide range of possible universes, it doest matter if you whant to believe in multiverse, cyclic universes, white hole universes, strings, simulation universes etc.
