I see this thread is still stuck in an endless back and forth between the people who insist that the Endless were not alive because the writers tell us so, and the people who say the writers messed up and what we are told clearly doesn't match what we are shown.
These two groups will never be able to convince the other, because they are not at the same meta level of discussion.
The former builds its arguments from within the confines of what the writers claimed our options were.
The latter point out that the writers could have written anything, and just did a bad job at this plot line because those needn't have been our only options, and shouldn't have, given what we carry over from previous expansions that really should have come up.
