Did we come from Mars?

Im new to ufology and things like stargates,many universes,structures on moon,mars second earth etc. I just got awake. I watch one of Richard Hoagland's video, the one which discusses about structures on moon and the other which he theorize that maybe humans could be from Mars!!!. Well it came to me an idea that, if us humans comes from Mars I mean our ancestors. Maybe they are the ones who wipe out the dinosours to make earth habitable for them. Maybe there comes a point on Mars that the planet is aging and somekind of cosmic process finalize its maturity and marsians were force to study the earth and makes it their home. Ok, why is that we dont remember high tech methods? Maybe our ancestors suppressed the knowledge because they want a simpler life because science could destroy or make a planet. And they new very well that humans had a potential of having to use science in both ways. Good or Bad...
