Go back to the beginning and reread. I have addressed what you call logic by pointing out the logical fallacies many times. It never took. You wouldn't even look up the fallacies I asked you to so you could see. So since you have proven to be impervious to corrections in your "logic", I gave up and am now just pointing out the nonsense of your "statements of fact". You don't "know" that time had to have a beginning even though you assume divine revelation apparently. No one knows if time is finite or eternal. That is why cosmologists are designing models to enable them to explore.
If you KNOW then tell them and save them a hell of a lot of work.
Saying time is finite isn't saying there isn't a lot to do.
Saying time is finite isn't saying the multiverse can't be discovered some day in some way.
Even if I could prove absolutely, instead of conclude with a logical argument, that time was finite it shouldn't change one thing that modern physicists are doing.
There is no reason to think it should.
