Do you have any reason why you think 'they' exist at all? Let us suppose there is some phenomenon that we don't understand. What are the possible explanations you can think of:
1. Your information is incorrect and the phenomenon didn't actually take place.
2. There is a rational explanation for the phenomenon without invoking anything extraordinary.
3. Some nefarious government agency is responsible.
4. God or some other supernatural force is at work.
5. Aliens did it.
Why do you think 5. is a reasonable option and why do you think it should be in the list at all? What about the phenomenon would indicate specifically a non-earthbound intelligence?
(and please don't say that some anonymous guy on YouTube told you so, so it must be true).
(nor is 'but you haven't ruled it out' a valid answer).
And the advice about online courses was in all seriousness. I think that everyone should avail themselves of the remarkable opportunity that is online learning. I am currently in the middle of two courses. One from MIT via edx on transcription of DNA and another from Yale on the history of the Early Middle Ages via Yale Open Courseware which you can find on YouTube.
I am just watching the videos and not doing all the exercises etc but I am still learning a lot. I have in the past done a number of courses on a wide range of subjects on edx where I did pursue the certificates (and passed).
I did sciences at University and was largely ignorant of other subjects. Online learning has enabled me to further my science education in areas I am interested in as well as venture into unfamiliar territory in other subjects.
