Hey if a person does not have to go to Church why did Jesus send his Apostles to the "Upper Room"?

Question

couldn't he have just done this last Supper at someone's house if being in a Church is not important and when everyone is just sitting around on the couch on Sunday morning, tell me how do they DO THIS IN REMEMBRANCE OF ME? as he says

Answer 1

He could not have done what happened in the upper room at the last supper.

Because he wasnt put to deaeth yet. "If I go not away the helper will not come"

If He didnt die, there would have been no holy spirit. The upper room was the receiving of the spirit, not the 1st church service!

Read John and Acts again

David

Answer 2

The upper room was at someone's house. It was not a church. In Acts the upper room is the place where they were staying, it was their home (probably rented) They did not have churches then the church did not start until Pentacost. But I agree with you people should go to church, not becasue of the last supper, but because the Bible tells us to not forsake the assembling of ourselves together, and particularly as we see the end approaching.
