This topic is essentially silly. There seems to be no sensible discussion to be had on the subject.
The only way the topic of the title would make sense is if it were claimed that it is possible to demonstrate that the Jesus of Faith existed through historical methods. But this is simply not possible - history certainly cannot demonstrate that Jesus performed even one genuine miracle - and even that would be insufficient.
Instead of that all we get is ICANT’s uninformed opinions on cosmology. To which I will respond that all the relevant experts disagree, which is a better argument than ICANT’s personal incredulity - which is all ICANT offers and very likely all he can offer.
