> What would be the other plausible explanation though?
Other plausible? However "Aliens" isn't the plausible explanation at all. The series' producer has a very specific agenda: to train the viewers to not believe the science (1) in his own words:
"It’s really a show about looking for God. Science would have you believe we are the result of nothing more than a chance assemblage of matter. The real truth is we don’t know."
Whereas in fact, science is also very much about knowing exactly what we don't know and where the limits of our knowledge are. Some people find that unsatisfying, compared to the wrong answers but giving assuring "certainty."
It particularly catches the people who won't attempt to analyze what is actually claimed there. 082349872349872 here (2) comments about how the claims in the series are constructed. I'd say "required reading" only to study how the underlying untrue "message" is packed in the series of non-sequitur claims, effectively navigating in the direction opposite of logic.
