If we were living on Mars, and made all the technological advances and such..then moved to Earth...where are all the habitats and such? Why would we move to Earth but not bring any of that knowledge/tech?
Right. It did come to my mind. I found the answer in "Pyramid of Egypt". There are more around the Earth which we still can not explain with our knowledge till now. So maybe we did bring the knowledge/tech.
But why we lost them ? To get this answer I take myself to Mars as of now.
If I go to Mars today, I will carry my Phone, Laptop, foods, oxygen (maybe) etc. So I am carrying some thing to survive and latest technology. I need electricity but I can not carry electric plant, which is so obvious here.
Anyway when I reach Mars, I must have this connection from Earth to survive and also have the latest gadgets running. By any means, if I get cut off. I will only have human power and energy with me to survive. My knowledge and skill. I will have to find ways to get food, shelter etc. to survive. Add to it many other like me and even some couples. We can imagine what will happen as the population grows.
I am not insisting that this happened when we came to Earth. It is just logical with what we are seeing here and what we know till now.
