  1. You forgot the innate hostility of space; the freezing radioactive airless void that is is, with interstellar space beyond that being even more hostile. Crossing that hostile void for thousands or tens of thousands of light years is clearly extremely daunting, even for robotic or machine life. If it was hazardous to send a handful of humans to a nearby body, a mere 384,000 kilometres away. Imagine to the nearest star (Proxima Centauri, a red dwarf with planets) 4.25 light year away. Since light travels slightly longer than a second from the Earth to the moon, then travelling a further 134 million times that distance?

  2. That advanced technological based lifeforms have not been found anywhere else is not an apriori assumption for their existence, just their rarity in the Milky Way galaxy. If we ignore religious suppositions, then the probability of human existence, a singular species of synapid primate mammal, is also very improbable through evolutionary hazards (e.g. mass extinction events) to Eukaryotes on Earth. Hence, for other extraterrestrial species as well, since they have not been detected anytime since our history. Until now. Attracted probably by the strong microwave emissions eminating from aircraft carriers, and the dozens of warplanes flying around them, maybe those unidentified robot flying capsules flying near there, with incredible inertia, might possibly be conjectured as of extraterrestrial origin.
