oOne day life will be kind...

Maybe, one day people will be kind.

I believe that one day people will live kindly, and love will be everything that needed for humanhumans need.

Once day they all will justall create fantastic things, will spend time with beloved people, they will search this beautiful world, and they will not think about such things as war and criminal thingse.

I supposethink that every person hasshould be able to live in a peaceful world and only think about theyir dreams and little problems, not about bombs, dictators, wars and blood.

Because there are so many prettiestr things that we can do and learn.

We have allthe cosmos wthat we dont know about, and I don't understand, I really don't understand why some people want makecommit crimes and kill another person's dreams and future when we have souch a big place forto searching.

It's too strange.

I think it's not right.

Look at the stars and understand: we are so little and we have so little time.

I want to spend my time with love and an opened heart.

Maybe, one day, people will be kind.

I believe that one day, people will live, and love will be everything that is needed for humans.

You could also say 'needed to be human'

Once day they all will just create fantastic things, will spend time with beloved people, they will search this beautiful world and they will not think about war and criminal things.

Because you use 'will', it sounds better to use 'will' to start off each section. As well, you can get rid of all the 'will' after the first one!

This is a really beautiful way to phrase this!!

You can also make this present tense "I want to spend my time loving with an open heart"

Once day they all will just create fantastic things, will spend time with beloved people, they will search this beautiful world and they will not think about war andnor criminal thingse.

"Will not think about war and crime" means they might think about one, but not both. Changing "and" to "nor" means they will think about neither.

I suppose every person has to live in peaceful world and think about theyir dreams and little problems, not about bombs, dictators, wars and blood.

"I suppose every person has to" is a little unclear to me. Are they compelled to? Or do you mean "in order for that to happen, everyone has to"?

"Prettiest" was a bit unclear to me so I took a shot in the dark.
