Can humans ever co-exist peacefully?

never becuse every person is individual in their ow terms,every person can't accept other persons view

I think it's possible for humans to coexist peacefully, but it will take something bordering on evolution to achieve this. perhaps a common enemy will unite humans. But someone will always have more, and someone will always want it.

Sadly to say I do not think that humans can coexist peacefully. I wish we all could, wouldn't our world be an awesome place if we had PEACE.

It is in human nature to constantly struggle for power. A peaceful co-existence would only be possible in a small community of, say, 100 to 150 individual who collaborate for the good and survival of everyone. Any larger than this, and the community would soon split in different factions, all trying to get the upper hand on the others. Sorry if the answer is a bit short and not fully elaborated, but I hope that it made it clear that a peaceful co-existence is only possible with a limited number of humans, and that the answer to your question is neither a complete 'no', nor a clear 'yes'.
