One of the major creationist criticisms of evolution is that it cannot be observed as it is happening. I'm just asking for an example of degeneration in action, since it should be easily observable in action. Are we seeing new, less-perfect sub-species of humans arising? Also, in connection to your biblical claim that people used to live 1000+ years, your only basis for that is the Bible. If creationism is to be more credible than evolution, it cannot have the same flaws that creationists accuse evolution of having.
It's worked reasonably well so far, but if you look at human DNA you see a lot more that's useless than useful.
Or, there is a large percentage of the human genome whose purpose we do not yet understand.
Degeneration in action? Have you seen the kids today?! :-) Ok, seriously, sub-human species is VERY possible IMHO, but who knows. My point was look at the DNA, its full of junk - regions of no use, no longer coding, or even foriegn DNA such as what appears to be no longer functioning proviral genomes. Cancer is completely genetic at the root. You see one does not have to develop new subspecies of degenerates in order to point to the fall of man.
You are complete correct that I have no objective scientific evidence that man every lived 1000 year, BUT find me a man that lived longer than 120 years, you won't, and this WAS predicted by the Bible.
Creationism is not without it's own gaps. That's why Creationists at our core believe what we believe based on faith, and when scientific fact can reasonably point back to the Creator of the Bible that only increases our faith.
Complete proof will not be available in this world, in fact to prove creation and God would be to negate faith, which is core to the salvation of the lost. Not only this but proof, for all practical purposes, negates free choice, allowing for service out of fear of retribution, rather than service out of love.

It is quite possible that we don't understand enough of the genome to understand every bit of what we call "junk". However, we do know enough recognize real junk when we see it in the genome. As to anything else, its like "dark matter" - it exists we just don't know what the hell it is.
