Post 4 : Time travel to the past or future

If i had choose option, i choose travel to the past. I dont have greats expectatives for the future, i am pesimist with the climate change, and these things the teacher said on her bloog, like natural disasters or lack of water etc. But if i could travel to the past, i would travel to the jurassic, only for see the flora and fauna of that time. See the dinosaurs or....a completely different fauna, i imagine a giant fauna, I remember an episode of the Simpsons when Homero travels to the past, to the Jurassic era, that's how I imagine it. 

However at the time it must have been difficult survive, maybe in any other times would be difficult survive for me, i dont imagine in other times without the technologys of today, the comfort of this time, i need a lot of technology for survive and not have them can be dificult. I wouldnt stay there for a long time, because doubt if i can survive with dinosaurs or with other wilds animal of this era. 

Another options, maybe can be the old egipcian, only for see how they did bulids the pyramids. I have heard many theories arround the piramyds,  that were built by aliens, because the three piramyds, Keops, Kefrén y Micerinos, match with Orion's belt, and they are also gigantic. How did they make this?, how so perfect?. I doubt these civilizations built them.
