As Warren has explained. 'as' is usually part of a comparison. (as big as/as long as) So, if there is a long queue somewhere, and you ask if you can be served first because you don't want to wait, the answer might be: 'No, you'll have to stand in the queue - like everyone else.' It wouldn't sound natural to use 'as' here. You could use it in a longer, comparative phrase such as: 'No, you'll have to stand in the queue - the same as everyone else does'.

as is either part of a comparison- he is as thoughtless as everyone else, or it requires a verb- he wore a cravat as everyone did at that time. like everyone else, the king has to take his trousers off to go to the toilet. like can stand alone as the verb is understood.
