First, the Bible never indicates the age of the Earth at all. Mr. Ham gets his misinformation from a mistranslation of the ancient Hebrew Scriptures, an interpretation made by King James, who had his own agenda. The original scriptures says the Earth was created in six "yom". It never says "6 days". Yom is the Hebrew word for any span of time, from a moment to an age or era. King James, in an attempt to make God appear even more omnipotent, chose it to mean "day", and translated it as such. From there, similar mistranslations were added, such as Moses being 900 years old. The original Scriptures, again, said "900 yom", and most intelligent people understand about "yom" take that to mean 900 moon cycles (months), or about 72 years - much more reasonable. Back then, there was no "annual calendar" as created by Caesar. Time was measured in the cycle of the moon - month. Even our own Native Americans used "moons" to describe time.
Based on the mistranslation by King James, a university professor in the 1970's, an atheist, used those corrupted figures to determine that, according to the Bible, the Earth is only 6,000 years old. His intent was to debunk the Bible, because science shows the Earth to be over 4 billion years old.
And so it came to pass that idiots like Ken Ham came to believe the Earth is only 6,000 years old. He never read the original Scriptures, and was sucked in to the BS of the atheist crowd.
Now comes the other idiot, Bill Nye. Nye claims Creationism cannot be true because the other idiot, Ken Ham says the Earth is only 6,000 years old. But what Mr Nye - an atheist - fails to mention is the simple fact that the age of the Earth has nothing to do with what Ken Ham believes. And he also fails to mention that nowhere in the Scriptures does it say the Earth is 6,000 years old. Mr. Nye appears to intentionally mislead people by using a false argument - that Creationism cannot be true because Ken Ham, who never read the original Scriptures, says the Earth is only 6,000 years old. That's like saying Creationism cannot be true because some mentally retarded person thinks the Earth was created when he was born. Just because Ham is wrong does not lessen in any way the possibility of Creationism.
What both Mr. Nye and Mr. Ham should do, if they want to be considered intelligent sources for a discussion of the Bible or creationism, is to read the original scriptures, rather than some translation. Until they do that, neither one knows the truth, and never will.
I have read the original Scriptures. I have also studied the sciences. And I can state unequivically that evolution and creationism are not mutually exclusive. Both are not only possible, but likely.
Objects without life - rocks, the planets, water etc. - cannot evolve. Yet, they exist, without evolutionary assistance. They had to be created. You can argue as to who, or how, but you cannot argue that they were not "created". Living organisms obviously evolve to some degree - the average height of a man just 150 years ago was five foot six inches. It is now closer to six feet. So, while you can argue that evolution, as detailed by Darwin, might be bunk, you cannot argue that living things do evolve to some degree. We adapt to changes around us.
Now consider - if there is a God, and He has unlimited knowledge and power, do you REALLY think He would not instill in all living things the ability to adapt (evolve) to changes in the environment? Of course he would. Even Proctor & Gamble evolves their products as times change.
So, to both Mr Ham and Mr Nye I say - get educated on a subject if you want to discuss it. Otherwise, you are merely idiots.
