If Jesus' resurrection was faked, why would twelve intelligent men (Jesus' disciples) have died for what they knew to be a lie?
Belief and intelligence are two different fields. Islamists blow themselves up and are happy to die for Allah.
How can something as small as a brain understand extremely complicated aspects of the universe, even though it is (supposedly) just a bunch of chemical reactions and electrical signals? But at the same time, this brain can’t create another brain like itself, so how can nature, that has no brain, create a brain?
We just haven't gotten there yet. Our ancestors' brains were preoccupied on not getting eaten, sex, and feeding themselves. It's only now with our technological advances that we can even begin to peer into the complicated brain processes.
Why can't this brain even create a simple living twig?
A living twig only appears simple.
Why is the simple cell likened to the complexity of large functioning city by experts?
Because it is not simple. It is only classified as simple in regards to more complex life forms.
Is it absolutely true that "truth is not absolute" or only relatively true that "all things are relative?"
I thought Christians were forbidden to engage in "vain philosophy" and "empty talk", since y'all already know everything?
What do you say about the hundreds of scholarly books that carefully document the veracity and reliability of the Bible?
It is important to note what portions of the Bible are documented as true and reliable. Myth and history tend to intertwine with the ancients, remember?
Have you ever considered the fact that Christianity is the only religion whose leader is said to have risen from the dead?
Elvis never died!
Why don't non-believers refer to Jesus as the late Jesus Christ?
Now you're just being obtuse.
If the authorities stole Jesus' body, why?
If the whole thing is a mythical embellisment of reality, this is a non-sequitur? The rest of the questions are rather similar.
How can one realistically discount the testimony of over 500 witnesses to a living Jesus following His crucifixion (see 1 Corinthians 15:6)?
Probably thousands have reported to see Bigfoot, the Lochness, aliens, etc. Seems like the mind is apt at deceiving or confirming our bias, eh?
Is it wrong to ask such questions? Why?
No, but it would be great if you actually took the time to look at both sides, instead of claiming you have the truth and expecting us to just follow along. I've been just as guilty as you have, just copy pasting things from creationist sites, and then claiming them as my own "thought experiments."
