Blue-green planet

Don`t you find it weird that the whole universe is so foreign to us. For example, your friends ask you to bring them around in your house but you actually do not even know your own house well enough to give them a guided tour. Many of you would think that my analogy is not even close to being apt. I beg to differ. We live in this universe for such a long time, yet, man does not even have technology which will suffice to allow us to visit and explore every nook and cranny of the universe.Or is it because it is due to other limiting factors and not man`s lack of technology. One may be that the universe is an illusion. We do not know what other dimensions there will be out in the vast and wide universe. Could it be that there are other Earth like planets or are the other planets only gas giants without sufficient water to sustain life. There are a lot of questions being asked, all the way from the astologies and scientists to the infants.The whole universe and formation of the universe is like a paradox, only that all the mysteries would ne unravelled one day. The Earth alone sustains over a billion lifeforms. What about all the planets in the universe added together? It is unbelievable. Yet, everything is real. We cannot possibly doubt our existence, correct? However, the whole universe is like an illusion. There may be danger lurking in any corner of this universe. The point is that we do not know. That is a fact, and facts are stubborn things.This is why the universe is an illusion which sustains all reality
