Robert Jackson's Life on Mars Theory

I theorize that Mars had life on it in the distant past. I believe that Mars was warmer at one time.Mars either had to be closer to the Sun or the Sun had to be hotter for this to happen.               I believe the Sun has been at a fairly constant temperature for billions of years.        I theorize that Mars was about the same distance from the Sun as Earth is today,at sometime in the distant past.                         I'll call this area of the solar system "the life zone of the solar system".         Earth is in the middle of this "life zone" now.         I think that Venus,Earth,and Mars are slowly pulling away from the Sun (for whatever reason).I theorize that this has been going on for quite sometime very slowly overall.                      I think that Mars moved very slowly out of the "life zone" and the life on the planet died out due to the cold climate and the changing atomosphere.                  The Earth at the same time moved further into the "life zone".                        Earth will eventually move out of this "life zone" and Venus will slowly move into it.I theorize this will take millions of years to do.      I theorize that when a planet first enters the "life zone"(like Venus will do eventually)primitive life forms will developed,as the climate and atomosphere become conducive for the life forms to developed.           I theorize that the Earth went thru this transition. For example: I theorize that during the time of the dinosaurs,that Earth was closer to the Sun and generally warmer.(around a million miles closer)             I think mars had a advanced civilization. This civilization died off due to the cold climate and changing atomosphere.                  Here are 3 other possibilities that I came up with for this to happen:      The Sun was hotter at one time and this enable life on Mars to exist,but this would of meant that Earth would of been much warmer too (maybe to warm for life or maybe not).                         Another possibility is that a huge object (asteroid or comet) knock Mars out of the "life zone". (there is no evidence of this that I'm aware of)             Another possibility is that Jupiter was a small Sun in the distant past and this generated enough warmth and light to enable life to developed and be sustained on Mars for a very long time (the orbit of mars and other planets would be effected by Jupiters increased gravitational pull) Mars may of revolve around Jupiter if this were the case.    I'm not a scientist,nor do I have the "credentials",but I do consider these ideas possibilities and may even be true.  Robert(Rob)Jackson 12-04-2006.
