"People are" is correct you can never say "people is" because "people" is always a plural noun and requires a plural 3rd person verb "ARE" :D

"people are" is correct. As in "Those people are speaking English"

People is plural, meaning more than one. In this case, it would be "People are".

a noun of multitude such as "people" correspond with the verb in plural form, hence "people are". A singular form would be "person" or "individual". :)

People are because people is plural. are = plural One/A person is...person is singular. is = singular
