Since I love to hear past histories or facts like how early people lived or survived during that period; How people started inventing or making new machines or tools? How the idea come up to the early people for making such incredible tools or machines? Are aliens really present in this universe? And if is, are they trying to contact us? And if not, Why are there so weired signs in different parts of the world? What is this sign means? How can early people make such huge monuments, temples in such an excellent way? How can they put heavy objects on top of the monuments or buildings as there was no machines? All this kind of questions of the answers I like to listen. Like ancient aliens in history TV 18 tells us about the aliens. So I love this channel very much. Everytime when I switch on TV, I first of all open history TV 18 channel.
