Did Satan visit other Planets?

This is a follow-up question from our 6-year-old grand-daughter who asked “Does God love Satan?”, which I expanded by incorporating common views. Children ask the most bizarre, and sometimes most challenging, questions!

A. Again, the Bible is silent on this one. The Bible provides answers to key questions that are essential to our salvation and Christian life, but also does not comment on a whole lot of subjects, including this. But there is an indirect clue:
* Job 1:7 The Lord said to Satan, “From where do you come?” Then Satan answered the Lord and said, “From roaming about on the earth and walking around on it.”
* Job 2:2 The Lord said to Satan, “Where have you come from?” Then Satan answered the Lord and said, “From roaming about on the earth and walking around on it.”
* 1 Pet 5:8 Be of sober spirit, be on the alert. Your adversary, the devil, prowls around like a roaring lion, seeking someone to devour.

Twice God queried Satan where had he been, and twice Satan replied “roaming about on the earth”. And the reason he prowls around is to devour people. His purpose is to create havoc on earth to destroy God’s people. He had no reason to roam uninhabited planets for curiosity’s sake. His main activities are to tempt and to accuse, and he wouldn’t blink an eye to lie to slander people. Since there are no people on other planets or in other galaxies, my opinion is that Satan did not waste his time there. But that’s only my view, with no hard evidence to support it.
