On the flip side, if you could time travel to that epoch, the ground would be extremely comfy for your feet.

yesterday someone posted a closeup of moss on a street to show how fascinating it is. i can't find it anymore, but it was cool. maybe somebody still has that picture?

Edit:

You're thinking about this like it's just a single uniform endless pasture of gray-green moss. But you have to recognize all the moss is competing for space and resources.

So you've got 40M years of different kinds of mosses all developing novel evolutionary strategies as they try to one up one another. Just a rainforest of mosses, with an uncountable variation of shapes and colors and compositions.

Moss bushes. Moss trees. Hanging mosses. Floating mosses. Dense spongey moss. Brilliantly colored moss. Poisoned moss. Cannibal moss. Stinging moss. Velvety moss. Venus Fly Moss. Moss of a thousand different color variants.

And every few hundred years, you get a new moss meta strategy for being the best kind of moss that pushes all the other moss out. Played across 40M years, it's this big squirling fractual of warring moss tribes, until finally another organism figures out the optimal play on all moss and then it's over as fast as it started.

Fortunately, there was no thinking until a very long time after that.

Well, not by life indigenous to Earth, anyway.

mmmm oil, or gas, or coal, whatever the moss ended up doing, it was something.

Just like there is SpaceEngine, we need a Earth sim that let's us to back to any time and have a realistic simulation of that epoch based on the best of modern knowledge.

Make sure you jump on that couch when you see one!

Thanks for make me realize that I had that big of a timespan to live in a beautiful mossy earth and I just missed it and landed on scorched land earth.

We stand no chance against the mighty moss
