I will offer responses/explanations to each of these, though they may not be my opinion, and then briefly describe my opinion.
1. You are not yourself omniscient, so what is a flaw and what is not is your opinion. i.e. You have no concept of bad without good and vice versa, since both are relative and subjective. So you could immediately make the argument that flaws are a necessary pat of a perfect universe, or that there's no such thing.
2. The Bible is filled with metaphors and re-translations; you can never really know what the original meaning of something was, or whether or not it was metaphorical, a parable, etc. since you didn't write it.
Also, since we were 'made in his image' and we feel regret, doesnt it follow that 'he' can feel some sort of emotion too?
[try to think of all these answers abstractly]
3. Again, many of these are parables and metaphors with very deep meaning. [Also Adam and Eve is not in the King James Bible s this would conflict with the 7 day creation story]
Why so many metaphors? Because some things are simply too difficult to truly comprehend, a story that the common man can/could relate to explains things in terms that a deeper part of himself might understand.
[Think parable of the mustard seed, another biblical 'story']
4. Noah's Ark is Old Testament, not New Testament, and the same things I already said apply, also 'With God anything is possible' applies here.
To summarize, you're reading it too literally, the overarching thing that you should take from it is that humanity itself has an overwhelming belief in a higher power. Whether or not there is one, it's the belief that means something, the stories just help us to relate that feeling of something larger than ourselves to a life that we're used to or can understand.
They help explain things that are beyond our ability to comprehend fully, assuming those things exist.
Also, people do not just 'make' a religion for some reason. Not usually anyways.
It grows out of thousands of years of tradition.
I suggest you read up on the history and variety of religions, you'd be very suprised.
If you want to see a view of christianity that gives a more literal view of the events that happened in Jesus's lifetime, I suggest reading some books by Edgar Cayce, a purported psychic who died about 60 years ago and talks quite a bit about the events of jesus's life, riencarnation and such.
Also I suggest you read up on Eastern religious traditions.
Feel free to respond.
Ah! I forgot to include my opinion...
I don't know
I don't claim to know
I may never know
I might not want to know
It may be impossible to know
To think that I know would be to think that I am the same as God himself.
I like to think there is one though, and I live by that assumption.
