>How NASA Worked Around Earth's Radiation Belts to Land Apollo 11 on the Moon
Humans used to be much smarter…
>what about the giants?
Yes. We used to be giants, too.
But we were still kinda smarter moar recently than that.
>Or is this where their DNA of us actually morphed and we have grown?
DNA plays a vital role in how we adapt to our environment. We don't need anything "genetically modifying" us or "gene-splicing". Our DNA does all that for us, by sensing our environment and making the necessary changes to whatever comes our way.
In terms of how that applies to giants, the force of "gravity" used to be much weaker back in the "before times". Couple reasons that likely contributed, but we see plenty of evidence for gigantism in all types of different animals, as well as plants, from that epoch. Humans were around for part of this, at least, and there is quite a bit of evidence that needs the right kind of common sense to apply in order to reach such a conclusion. The gaslighting is real, though, and false concepts are inserted at such a young age in the indoctrination process, most people will never get to see, and even if they do, they are [programmed] to reject it.
"Evolution" is taught to con the ego into believing it's the greatest thing ever. Yet, it's a false teaching, and it greatly obscures the beauty and POWER of Nature. As stated above, it is "Adaptation" to environment, not linear "evolution" or crazy conspiracy theories, like Darwin's.
