Although you keep the idea about the beings from the other worlds in mind for a long time, and there are many arguments for it, it is still just a probable assumption. It is very unlikely that there are inhabitants – yet still somewhat likely. You have no right to state firmly “yes, there are” until you personally make sure that there are certain beings. To be more accurate I should say it is possible that they exist, but it is also possible that they do not. Think about navigators. A navigator comes to an island, and everything points to the fact that there must be some inhabitants. However, when he gets ashore, he sees nothing. Alternatively, just think about the ancient times when people have not multiplied yet. At every turn, you could meet the signs of undeniable habitability, while there were no inhabitants at all. The same is with the celestial bodies – there are plenty of hints that they are inhabited. What is more interesting is that whether they are still waiting for their inhabitants or there will be none at all: who knows what is the Lord’s will concerning them! We need to visit these worlds and make sure before to say firmly “there are”. Otherwise, we cannot say more than “probably”.
