Well, no it doesn't. Everything isn't at face value, we've learned that at this point. There's a lot of deception going on, both movies of phase 2 have shown it.
People were speculating on whether or not we got the full story. I don't buy that Malekith created an infinity gem either. Please explain to me how that is not paying attention.
The fact of the matter is that we have no idea what the infinity stones are, they certainly don't fit in the gauntlet. For all we know, the energies of these gems could exist, somehow left the gems, and were put into these stones. Malekith could have come across the energy of one of these gems, and tried to create a weapon out of it.
He may have created the Aether, but I don't think he created an infinity gem because the stones more than likely aren't what make up the IG. I think he used the energy of it to make a weapno, or a holder of the energy, the Aether. Sure, it may be an "infinity stone", but a lot of people seem to be taking it as he created an artifact that Thanos will plan on using in the IG, which to others seems just wrong....it may be. I bet the energy of the Aether wasn't created by Malekith.
Now go ahead and tell me that I wasn't paying attention. Cause I was. Again, no need to insult people because they see things differently than the majority. It's childish, and you have no right to judge someone's thinking process just because from your POV it would appear they didn't pay attention.
