I don’t like to talk about this because it’s impossible to put a positive spin on it and I think we’re going to have an entirely different future from what “they” intended but here’s a couple of the many possibilities:

1. A worldly option is they took their opportunity to exponentially increase their global DNA database. It’s an effort that’s been going on for years at a smaller scale, the mormons, the israeli’s and others. Some of the reasons are benign, some malign.

This would put large scale data in the hands of the controllers and I’m sure our guess is similar as to what they’ll do with it. Look for weaknesses to exploit like any good enemy.

2. Otherworldly option - these people are obsessed with ancestry/origins, and if they have been collecting DNA, it’s an absolutely bonanza for connecting their dots. They believe they’re descended from an (almost) extinct, non human race and want to find both their kin, and others that may be exploitable based on their genotype.
