Or in an age free of disease and inferior food, people lived to incredible ages. There's no reason for a year to be anything other than the solar cycle it has always been.
Where did you come up with they didn't have disease and such?
They didn't have a lot of things. Grape juice used to sit on the shelf without fermenting, which is why Noah discovered intoxication after the flood. People stopped living for hundreds of years as the age of disease started. People also started eating meat because plants no longer sustained nutrition by themselves. This is all in Genesis.
genesis is obviously wrong.
They have found parasite eggs from the Celtic settlement in Europe
Cancer in cavemen
The bible itself talks of alcoholism, fever, itching etc. They just didn't have the means to "diagnose"
Although, I will give you, the biggest killer in the "bible days" was god himself
The biological fulcrum of human history is the flood itself. The very laws of physics changed forever. Wine did not ferment, meat was not eaten, and the body wasn't broken down by decades of relentless assault by armies of bacteria and viruses. As a fan of science, I'm sure you can appreciate that bioloists are generally agreed that disease is what causes the aging process. For men to live 969 years like Methuselah, disease would have to be absent.
God said that so many years gave opportunity for much more iniquity to answer for so out of an abundance of mercy, he said he would limit man's age to 120 years. Disease was how that was accomplished. The age of highly nutritious, age defying fruits and vegetables also ended and to supplement the new deficiency in plants, God told Noah to start eating meat. Fruit juice which could sit at room temperature for weeks now began to ferment and spoil. Noah was the first man in history to get hammered...and by accident too.
This is all recorded in Genesis and it really isn't such an outlandish sequence of events.
