That timeline reads like something a 7th grader would write, and the problems start in the first entry.
3502 BCE
Indogene scientists begin tracking a rogue star that is on a collision course with their own solar system. They theorize that the resulting collision will wipe out all life in the Votanis system. The Indogenes warn the other races that they need to begin planning an exodus. The other races don't believe them, and balk at the astronomical cost of the proposed Ark fleet
A rogue star wouldn't "collide" with shit. It would certainly disrupt planetary orbits if it got close enough, but that wouldn't cause problems for an advance species. You just dig in and live underground. It would take hundreds of years for a planet to get tossed out of a system.
And there being multiple intelligent species living in a single solar system? The odds of that happening are literally astronomical. I mean, humanity once existed among other species, and you don't see many neanderthals around these days, do you? We either killed them off or bred them out of existence.
Here's another gem:
2025
Global war makes delivery of fossil fuel to America problematic. Nuclear energy gains prominence and many new power plants are constructed, including one along the Mississippi River in St. Louis. As food and energy become scarce, people become desperate, leading to a number of human/human and Votan/Votan side conflicts.
It takes decades to build a nuclear power plant, and that's not counting all the regulations and shit. It's a massive undertaking, and they're building multiple plants in a matter of a few years,
during a fucking war. Can you say "bullseye"? I mean, Israel and the US want to bomb the shit out of Iran for building a single nuclear plant because it could be used to build bombs, but apparently the Votans think these plants are just for power...
You know what? I know what my problem is: I'm a few years out of the 18-35 demographic that SyFy targets for all their shows. Combine that with a healthy science education, a love for
actualscience fiction, and some critical thinking skills and it's no wonder why I can't enjoy any of the crap SyFy has to offer.
