salam, saha ftorkom
i just want to say that first, may be man discovered the space but he steel know nothing about it even about our planet , , the oceans , the fact of yajouj wa majouj & other lot of things , also when u talked about scientist and philosophers i think that they can just suppose & imagine and because the human mind is limited so it can't explain all the things that made by a god, and most of them are atheist and other serious fact about the aliens , let me tell u my brother that it's just a lies just illusions wich are made by the zionist , they just tried to make people feel as in movies that we are in danger and america will help us it's the brainwashing my friend.so don't believe all what you see or all what you hear.
in the end i hopr that this comment will be helpful
peace be upon you
