Identifying aircraft or atmospheric phenomenon is very complex. You need an understanding of aircraft and various classes of aircraft. Satellites and various classes and orbits. A for phenomenon you need an understanding of physics, fluid dynamics and meteorology. It's easier to say you saw an alien.
Technology has advanced significantly in the last 200 years. This makes senses in you understand the enlightenment and improved communication technologies (printing press etc). There has been a steady increase in technological development each one making the next feasible. Optics improved reading. Lighting allowed work outside of daylight. Agricultural development allowed more people to get out of a substance living and more people developing technology and culture. Unless we got all those ideas from an alien craft.
Vaccines and how the improve immune response is not trivial. Especially the new vaccines that were developed for covid. Rather than appear ignorant, it easier to reject that they are effective.
