Why animals need to sleep is actually not known. There are multiple theories though.

I think we should try to figure out why and put an end to it.
Sleep takes away too much time from life.

>Why do animals need to sleep
Don't know. The grand "why" can be hard to answer because it's different than just the sum of its parts. We know a decent amount about what conditions spur sleep, and why those arise. We know some of what happens during sleep. But the whole picture, and "why" is it that way, is bit more difficult.

>but cells,
Cells have their own cycles. Some of those stages are comparable to sleep. Sleep is not stasis.
>fish
Fish sleep.
>and trees don't?
We don't really know much of anything about the self experience of a tree. We barely understand our own consciousness enough to stumble along trying to hack together a half functional definition. You could say deciduous trees "sleep" in the winter, though.

sleep is needed because the brain has shit to do that would impact normal alert thinking

things like cleaning waste or healing itself can be done better when most of it is "off"

additionally animals with brains don't NEED to be active 24 hours a day, you can get all the sustenance you require and then some in just a few hours
by limiting your active time you limit risks

there are also some theories that your brain needs time to garbage collect and store memories in some meaningful way

of course all these things are pretty much guesses at what our consciousness is
until someone figures out a way to interpret the way a brain stores data and how/why our brains do half the random shit they do we wont know

Honestly I think it pretty much comes down to this. there is a huge, 50% portion of the day that is too dark to function, so animals just started shutting themselves off to conserve energy. the other benefits came later.

Anything with a ganglion needs to sleep. Cultured neural networks sleep.

sleeping is the natural state. being awake is just the active time to eat , drink and have sex.

>fish and trees don't
At least some fish sleep, one half of teh brain at a time.

All good and fun until the cat takes a dump on you.

I once had a dog crawl up to the top of my head, scared of a massive thunderstorm. Very cute afterwards. And rather scratched up at the time.
