How can you know there is a connection if you cant think what they are? Im a bit confused because that justification could work for anything.
How do you know?

An example is:
Personal opinion with no fact: I think angiens are linked to necro
Personal opinion with fact: I think angiens are linked to necro because on the gate you can clearly see an angien carved.
The difference is one is a guess/theory (And theories are good, so no issue there) but it isnt backed up with anything. The second has a backing, it doesnt actually explain much more than the first but shows you have thought about it and did some research (and found something).
I think these kind of posts, if they are to work, need to start with "Here is something I believe, here is some reasons why I think its true, Do you have any opinions" because it shows you arent just asking for answers and opinions (which may have taken much research and time to reach).
