That seems like it would require a lot of faith.
The whole reason no faith was required to hypothesize the Big Bang, is that everything looks like that's what happened. Pick a direction (any direction) and the further-away stuff is moving away faster than the closer stuff.
If you're looking for faith, it's here, but it's not that. The faith required by science is that our senses sense reality. That is the completely-unfounded religious axiom of every scientist: that the universe is as it (roughly) appears to be, so that the nature of reality can be inferred from observation.
It may be incorrrect, but no one will ever know, because their senses are all they have to learn from. You might be merely imagining that you are reading this, when in reality, I never wrote it because I don't even exist, just like every other "person" you mistakenly think you've observed or even "met."
