Regarding the Big Bang, I don’t know, you really don’t know what you’re talking about. The scientific estimate of the age of the universe is not based on how long light took to reach us. Nor is it based on whether there are parts of the universe which are not visible to us; it is assumed (reasonably) that there are.
