The space guide promised that every alien on this planet is friendly.

The space guide promised that every alien on this planet is friendly.

We use every with singular countable nouns (like "alien"). "All" and "many" would require the plural form "aliens".

However, the police noticed that all their spaceships were illegally parked in the meteor lane!

We use all before possessive adjectives (like "their") and plural nouns (like "spaceships"). Words like "every" or "much" cannot be followed directly by a possessive pronoun and a plural noun.
