You are applying non-science, to a topic, and calling it science.
If I said 'Here is a doctored photo of a spaceship landing and dropping off unicorns, and the real photos were stolen by people who didn't want us to know Unicorns were really Aliens. Therefore, there are spaceships dropping off unicorns in the woods. Unless you can prove otherwise.' Then you'd think I was being silly.
But as soon as 'Giant Human' gets into the mix, it is all of a sudden a valid scientific endeavor?
There is no fossil evidence of giant humans. The stories are written to make you think there is evidence. They have fooled some of you.
Bipedalism has it's limits, spreading a huge mass over two points of support is taxing on lower limbs, spines, and hearts.
