In an indirect way, we did "meet" some enemies. I'm fairly certain the mysterious attackers of the base are going to be the main baddie. When they aren't, well, trying to survive on an Ancient ship. I'd have to suspect they didn't want them to get the Gate working, found out they had the right solution and thus showed up to shut them down. They didn't directly confront the ships in orbit, but focused their attacks on the planet. If that's really addressed in the first half of the season or in the first season at all, who knows? I rather hope so. Because I've lived through this we're barely surviving out here schtick for three years watching the old Lost In Space and it's not particularly interesting to me.
