The man in the green suit exhales. He continues, patiently.

"We can't confirm anything here, but everything we have points to a race called the Ohm traveling between dimensions killing worlds. I've been on an alternate Earth stripped of sentient life by a nanite bomb. I've heard the remnant distress call we found there. I was there when we managed to make contact with a species called the Daligig that explained this to us. Can I tell you if they're lying to us? No. But it's all we have right now."

And until he can find proof of anything else, he'll go with it. It's not like he has a lot of options, and none of the others seem any better. They're flying blind.
