Welcome to the forum.
"Attend" is a verb so I'm not sure what you are trying to say.
Sentence 1 does not make sense at all. "We are attended" is ungrammatical and "to make a cook" means nothing.
Sentence 2 has problems too. Again "We're attended" is ungrammatical.
Are you trying to use the past tense of "to attend"? If so, it's just "We attended", meaning "We went to".
