No matter how many times you restate this, it doesn’t appear to be logical.
We draw them because we have seen the historical representations and because we have the fossil record. In the times when the original cave drawings and the like were done, there were no fossil records to speak of because they didn’t possess the technology to reconstruct the bones.
We are not at the beginning of this discovery but somewhere way down the road, so everything we do is from historical evidence and hearsay. Everything they did had to be from first-hand perspective if it was to be in any way accurate.
Nice try, though.
I don't buy that in the slightest. How do we know what the dinosaurs looked like? We find the bones laying around. Do we put them together perfectly? No, but we still know there were big dinosaurs. Why couldn't a human who found big bones 3,000 years ago surmise that they came from big monsters?
