Answer:
1. Observation is a scientific method, anything observed does have some scientific basis but at the end of the day, superstitions are just that, superstitions and not scientific fact so basically no.
2. Superstition always comes from not knowing, combined with awe. The celestial sky, seen in the already mysterious and frightening dark night, was very impressive, and from very early associated with supernatural powers like gods. The gradual annual change was studied to get a grasp on time and the predictability of the recurring patterns gave people the idea they somehow had a grip of understanding. The erratic but also in a more complex way predictable movement of the planets did a bit of the same; they were associated with godly patterns and priests borrowed part of their standing from interpreting these planetary patterns.
3. Conduct more studies about it, trying to understand their orbits/patterns, chemical compositions, and look for signs of life.
