Unless I'm mistaken or misled of course
Imagine humans would have 100% control of their genetic materials. If they were to settle on too hostile planets they would alter their bodies to fit the environment. We obiously still would have a free will.
Thanks for backing me up Flaser
The reason shivans are using ships and they don't seem so 'alien' is that they cannot.
Shivans have no way to exist outside subspace, they would simply die if they ever left it. The only way to get straight to us for them is to create physical bodies, half robotic and half organic (much like a space suit, only even more extreme). Thats also the reason why they build ships. Yet where they can they remain using energy: - they prefer lasers - they have beam cannons (first) - they have some kind of plasma claws as weapons.
Can also be seen in their transport, all those sparkling thingies. This also explains the red pulsating stuff on their ships.
--- kinda off topic now, but some additions to my theory:
Shivans seem to have a liking towards nebula regions, that's where they come from, in most cases. That's perfectly explainable. While watching the 'Bosch in the Nebula' monologue again, I realised that a nebula is indeed the remnants of a super nova -- just like capella will be. Thus the point in space where the subspace barrier will be most stable, is around nebula regions. And who knows? Maybe Gamma Draconis, was the downfall of the Ancients. ('Have the shivans been waiting for us..... all these years?') - Bosch realizes that this very old nebula (maybe millions of years old) might indeed be caused by the shivans, just like they will later on blow up capella. That's probably for the first time that he notices HOW old the shivans indeed are. That's also the reason why he does feel so insecure and uneasy. The shivans are millions of years old -- and probably nobody had succeeded in achieving what he had planned.
