gollark: Why would they not:- look at stuff from orbit beforehand, or send unmanned probes- have at least basic weaponry available for defense against possibly hostile native life- have waaaay better medical technology and/or environmental protection stuff, thus making the deinosuchi not very threatening
gollark: Oh, and they need good shielding against high-velocity particles, which might work okay against some weapons fire.
gollark: Any drive capable of bringing you up to ridiculous fractions of lightspeed will have a horribly dangerous exhaust, the power sources necessary could also run tons of weapons, and you can use said drive things to, I don't know, accelerate asteroids to high velocities and crash them into planets.
gollark: Ah, but their ships themselves would have to be weapons to travel interstellarly.
gollark: Technologically speaking.
