“There is a lot of fraud (think Piltdown man)”
One.
One fraud.
And caught by scientists.
AND made it harder to conduct future frauds (archeoraptor)(cold fusion).
“and a lot of misunderstandings (Neanderthals were suffering from lack of vitamin D).”
A claim, sure. Got a cite for the proof?
“Before the flood the air was heavier, and richer.”
Cite?
“With the changes of the flood, dinosaurs could not live. (except for the deep water types, like Loch Ness Monster).”
Um, most estimates of the Loch Ness Monster do not identify it as a dinosaur.
“Therefore they were killed in the flood.”
THis adds quite a bit to the Narrative of the Flood. The Bible says not to add shit to scripture. Says it in a few places.
God did not direct Noah to save a select few animals, the ones that were not going to die off in Futureworld.
“They might have been part of the Almighty's original creation, or they might have been the results of genetic experiments.”
Just feel free to ad lib anything necessary off of holy scripture.
