Just got into work and my you lot have been busy!
So excuse the quick recap
Russ, re the red mineral in the nile, it happens to this day as well.
re the Noah story, literary evidence shows when it entered hebrew culture, and that it was in messopotanian culture long before, ergo the hebrews adopted it from them (it can be pinpointed to when they were their slaves).
Again, these experts who come up with the explanations of how these "miracles" happened are not saying that they weren't caused by god.
Now, you said that many things in the OT are wrong or incorrect, but how can this be if the words were given to the writers from god?
You could say the writers being just men could have written it down wrong, so why didn't god correct them there and then rather than letting his people wander off down the wrong path?
Prepare to wince. In genisis, god says that to show you are one of his people you must be circumsised

Was this decision ever revoked? If so, what are we to make of a god who can't make his mind up?
If it wasn't revoked, then if you are uncircumcised, then you are not one of gods people and therefore not following his teachings, therefore failing him.
Can anyone put a case forward showing that (by his own actions) god is not a genocidal tyrant?
