Well I think it depends on what one thinks the science says
Science is a methodology. It doesn't "say" anything. What you "think science says" has absolutely nothing to do with the truth.
Now now, I didn't say science says or confirms what I believe in. I'm was saying, that our understanding of our universe, changes from time to time.
But -
The hypothesis that dinosaurs and giants had gladiator-style fights lacks any evidentiary support. It can be dismissed with the same confidence as the hypothesis that there is a purple unicorn living in my garage.
Not really the same is it now? I mean...to state the obvious, the differences between the two. The ancient buildings of
collossal size, e.g,. Baalbek, and those structures in Russia actually EXIST. There pics of large skulls floating about but of course depends on the source. Controversial this may be, BUt, there's something there at last to debate about. Whereas your 'purple unicorn' which you confidently "reason " to be comparable without any thing similar is rather over confident?
