What is the meaning of life and give a good explanation if you want brainiest

The life a being that grows feeds itself reproduces and they die as we know them humans, as such some of the humans believe that they are the only species of intelligent life and that they are alone in this vast universe but I tell you we are not the only ones, And if you think I'm one of those who believe that aliens exist but I'm not crazy and I have not seen them and I really do not think they've visited us yet, but if I think they exist, just imagine that it would be ridiculous with so many billions or surely trillions or numbers that we have not named planets that are outside do not have good life just wanted to let you know that.

NOW

How do we exist?

really this is not confirmed or anything like that but what IS confirmed is the evolution therefore if it could be that we come from the monkeys and say BUT WHERE THE MONKEYS COME FROM? Well, I would tell you that from other ancestors and you will continue asking the same thing, I will tell you how life arose, so prepare yourself because this is the beginning of life on Earth.

When the Earth formed there was absolutely no life or water until comets that contained water and a strange way of life was an evolutionary bacteria after the comets fell and spent a few years the bacteria evolved but there was no oxygen but even as the bacteria evolved without the need for oxygen because it was in the sea and coincidentally this type of bacteria expelled oxygen like a plant after thousands of years there was oxygen in the earth and some of the bacteria evolved as fish those fish would become predators of the smallest fish and this was the beginning of life in the sea, after that a bacterium was out of the water and if evolved to adapt to breathe oxygen evolved and evolved in different animals of the prehistory like dinosaurs, mammoths and primitive animals after thousands or millions of years it was the great ancestor of the monkey that did not know what it is called xD and if it evolved to the ancestor of the monkey we know is the monkey evolved 4 to 5 times 1-first monkeys 2-ancestral monkeys 3- homosapiens (some) 4-another type of human monkey without counting others because there are like 6 and 5 monkeys today if you do not believe in this of evolution because you will have to go to religion because there are only 2 unconfirmed theories as I see you believe in evolution and people who say that if we come from monkeys as even monkeys are still alive, I SAY IF THE DONKEYS COME OF THE HORSES BECAUSE THE HORSES LIVE? Well, tha's all. I hope this one has helped :3
