If you put some play-doh in a jar, and then some ants along with it, the ants would shape the play-doh into their world. It would become their world.
And over time, the ants would evolve, they'd become intelligent. And eventually they'd wonder where the play-doh came from. What it is, what made it, what was here before the play-doh, if anything.
Ants don't have any idea that there are humans around. They don't know why some of them suddenly are crushed or burnt. Why their homes get destroyed. The same way they don't know why rain comes down or why some ground is hard and some is soft. Humans move too fast for them at their level. They're on a scale too grand to recognize. Another plane of existence.
So they'd continue coming up with theories for why the play-doh is there, and never any evidence why.
