entities in the world above

imagine if on a low-gravity world there were huge creatures that were so big and tall that they had long legs and they were a sort of "mass above the ground supported by their legs" made of flesh and skin and with things to eat the trees (they are taller than trees)
so they would be like a large-scale organism with an "evolvable complex fractal-like body" like plants
kind of horrifying but also pretty epic
maybe in the universe above (assuming htis is a simulated universe of sorts) there existed these creatures
and they had to be immensely intelligent and complex to survive, so much so that they were competing for resources and space (maybe even very high-dimensional space) just to allow them to exist to different extents
and their minds are immensely complex like a combination of both a singularity and a hivemind so that different parts can both act as one or individually/separately
and one eventually won, consequently one of the most intelligent, and that one since nothing was competing with it decided to create worlds
and it created complex abstract mathematical frameworks and patterns and built structures we can't even begin to imagine
and created this universe
one of many
in this universe above there would be entities like the one I described which are as big as planets in "our scale" but the actual "places" they existed in would be far bigger
and the timescales and spatial scales would be absolutely enormous
