If you are starting at zero there is a big learning curve, but if you're into it, it is a lot of fun.
What I can't understand is atheists who balk at the possibility of any kind of god, but happily entertain the notion that we are in a simulation. What exactly would be the difference in a created reality and a simulated reality?
"In the beginning God created the Heavens and the earth..."
I don't share beliefs with Ken Ham, but what I see the Bible claiming about creation is that it was directed by an intelligent being (or beings, the number is vague in this text). Seven days? Sure. What does the word "day" even mean when there's no sun yet? In that case it means however long it took for the miracles described to happen. There were no words for time dilation or quantum mechanics or background radiation then. I'm assuming there will be more concepts concerning the beginning of time and the nature of the universe that we currently don't have a word for. The people who first wrote down that story weren't stupid. They weren't intentionally writing down contradictions. They knew there was no such thing as a day without the sun. They were describing a miraculous progression of creation. It wasn't science (even such as it then existed) it was religious narrative. The goal is not to get a reader's assent to the facts of the details but to point to a creator with power and purpose.
Your second question could be asked of any human I think. How much of this do you really actually believe is real or important? How often do you act on what you say you believe? I suppose it seems more scandalous for religious leaders because of the nature of their claims, but at the end of the day we're all just people.
Your third question is fascinating to me too. It is fun to read really good authors and historians explain their theories on this, but unfortunately it's all guesswork. The question is good though, because I feel like most people make broad assumptions about the sincerity of other times (and other cultures and religions for that matter). You've even done it to a degree by assuming what was important to the Greeks. Which Greeks? They were at one time a collection of city-states with competing interests. They were at another time an empire lead by a Macedonian. There are so many different peoples and times that we tend to wrap up and summarize as "Ancient Greeks".
I'll end by saying, I got to where I am (faith) by continuing to doubt. I tried to ditch my faith at different times, but I kept having nagging belief I couldn't get rid of. That part I still haven't figured out how to explain.
