Was it ever explained how the first stone came about? Do they have a "Origin"? If I recall correctly, The Stranger was the first person to come across the gem, then Adam Warlock. I know that The Collector was the first one to mention The Elders during The Korvac Saga. I know that The Gardener always had one. Didn't Moondragon also have one BEFORE Thanos got the Gauntlet? When (And how.) did The Elders start getting a hold of them? Thanks.
