Earth and Mars: Sister Planets?

Question

Was there a time when Mars and Earth were related by a common feature: Life? Could Mars hold the key to life on Earth and also explain its short demise of its evolutionary pathway?

Answer 1

Earth and Mars, though different, could still be considered sister planets. They are the only two in our solar system located within the habitable zone of the sun. Mars is only colder, because it is half the size of Earth and farther away, had it retained a thicker atmosphere however, it would be warm enough at all times for life to exist.
I think it is highly probable that small organisms and bacteria still exist somewhere on Mars, perhaps underneath the frozen seas of Elysium near the Martian equator. Mars is one of the only places we know of that is anywhere near capable of supporting life. Temperatures there can dip to -167 degrees Fahrenheit at the poles during winter, however equatorial summer temps, can rise above 80 degrees. While we find this mostly far to cold, there are organisms on earth (extremophiles) that live in the antarctic, where most martian conditions are matched.
Mars air would be toxic to us, however if it was warm enough, plants could feasible survive because of the abundance of carbon dioxide...so yes, I think that Earth and Mars could be related in more ways than their physical similarities, life could be a common factor between to too, though life on Mars would be much more primitive due to the extreme climate.

Evolution is not true and cannot explain life..if life was ever created on Mars, it could have survived and it may not have, we will have to go there to find out

Hope this was useful

Answer 2

Mars shows signs that life may have existed there long ago and it also has an atmosphere similar to Earth's. Since Mars is probably the closest planet to Earth they could both be related by Life at one point in time. Yep, it's likely.
There still may be life on Mars, who knows. Microscopic organisms if possible.

Answer 3

I did work for NASA and have looked at lots of pictures of Mars , It bothered me that there are many dry river beds and some giant canyons that appear to of been cut by running water. Now considering the temperature on mars ,it had to be much hotter ,so what was the temperature on earth at that time.

Answer 4

Not likely.
