Men have tried for thousands of years, but have never proved a single contradiction.
Most who try are not truly interested to see if there are any logical explanations. Instead they want to find flaws because they don't want to submit to the Biblical teachings.
If there is any logical way a scripture could be true, than no one can say there is a proven flaw in the Bible, but many want to discard any possible way it can be explained.
Again, no conflict has ever been proven in the Bible even though there have been some people trying for thousands of years!
---- Edit -----
The "contradictions" you have listed are the same old ones that have been tried many times before!
Differences between Genesis 1 and 2 are not contradictions, but they are the same thing described in two different ways. Genesis 1 is chronological; Genesis 2 is not.
The Bible never tries to be a science book, therefore, it may not categorize things in the same way as modern day science. The Bible, for example, does list bats with birds, but the Bible tends to list all flying animals as birds. This is not trying to categorize them based on species, but on the fact that they fly. Also the "scientific" categories were probably decided upon (by men) AFTER this was written in the Bible.
Many people call wahles "fish". Scientifically, whales are not categorized as fish, but most people who refer to them as fish anyway are not trying to be scientific. (Whales swim and look like fish, therefore, many people call them fish.)
The Bible is a book about serving God, not a book of modern science, therefore some of the terms in the Bible may not match scientific terms that were established, or even changed, AFTER the Bible was written! Just because what the Bible calls something and what a man (or group of men, whether they be scientists, or whoever) call something is not the same, that does not mean there is a contradiction in the Bible.
As far as that goes, there is often a contradiction between the Bible and things men decide.
But, as you have said, there is not enough room for you to list all of the alleged discrepancies in the Bible, and there is definately not enough room for me to respond to all of them (since it takes less words to list an issue that it does to discuss it)!
Look at the link I have provided. This web-site discusses all of the suposed "contradictions" you have listed and more.
