How to Use 'Almost' and 'Most'

　I'm sometimes confused by how to use ’almost’ and 'most'. So today, I'd like to make a note about correct examples and wrong examples.

Correct examples:
・almost all scientists...
・almost all of the scientists...
・most scientists...
・most of the scientist...
・(the) scientists mostly...

Wrong examples:
・almost all of scientists...
・almost scientists...
・most of scientists...
・most the scientist...

I really often make a such mistake. If I say "Almost people are...," this might imply an alien which is becoming a human. I'd like to be careful.

• ・most of the scientist...
• ・most of the scientists...

• ・almost all of scientists...
• ・almost all of the scientists...

• ・almost scientists...
• ・almost all scientists...

• ・most of scientists...
• ・most of the scientists... / OR most scientists

• ・most the scientist...
• ・most of the scientists... / OR most scientists
