Everybody knows that [...] VS Everyone knows that [...] [closed]

I was wondering if we should use one expression rather than the other?

For example the sentence could be:

Everybody knows that global warming is an important problem

Or

Everyone knows that global warming is an important problem

Which is better? Which is mostly used for reports?

Solution 1:

Everybody or everyone would normally have the third person for subject-verb agreement. So everybody or everyone knows is correct.

As for the choice between everybody and everyone, that's a matter of taste:-

usage: Everyone and everybody are interchangeable, as are no one and nobody, and someone and somebody. Care should be taken to distinguish between everyone and someone as single words and every one and some one as two words, the latter form correctly being used to refer to each individual person or thing in a particular group: every one of them is wrong

Solution 2:

I can't think of any situation in which the following is a correct usage of grammar

Everyone know that ...

It would have to be

Everyone knows that ...

That said, everybody and everyone are mostly interchangeable
