Is it possible that humans originally came from Mars ? Is there any 'hard' evidence for this ?

Could be, it seems strange to me that homo erectus lived on the Earth for 50,000 yrs, then came neandertal which lived here for 450,000 yrs and never got any smarter, and last but not least, homo sapien who was here for 50,000 and only started to prosper in the last 250 yrs? Sounds like outside help was a factor to consider........you Bible thumpers need to go hide in your religion category! If yall trully followed your religions you wouldnt be usin them cell phones, cars, tv sets, PCs, etc! An open mind created these things! Not some blathering boob who didnt have anything better to do than chew mushrooms and claim to have talked to the LORD! ALL matter in the universe came from elsewhere to begin with!

humans are a form of animal life that depends on a lot of natural resources. Our bodies are mostly liquid water. Our blood is similar in make-up to sea water. We need to eat foods including vegetation that can not grow below 0 C or above 100 C.

The average temperature on Venus is 450 C. The temperature of Mars ranges from 150 below zero C to about 10 C.

Neither planet can produce the kind of life that could become us. There may be life on Mars. There may have been water and other forms of life there too long ago to be of any consequence to us.

But we did not come from there. We are members of a web of life with countless species which have similarities to ourselves.

;-D We are Earthlings. We are Terrans. We are Humans. Take care of our home. It is the only one we have.

There so much that the world does not understand. Existence did not just bust forth from emptiness. Look friends, Every study make a good pointer that God is true. There is a best to your comprehension. The walk with God is not fruitless. Yes there is a pre Adamic age, aleast report have proven that, but bear in mind that there is a power or a force beyond science and research. You can not prove to me you know the power that keeps the earth moving in its orbit and axis. You may not even define how the entire universe came into play. God is true!!!!!!!!!!!!!!!!!!!!!!!!!!!!! friend. Jesus is faithfull. Genesis 1:1 to :2 is a very long time. From Adam till now is just about 6000 years plus.

Well I know a few people who seem to have come from Mars but in actuality there is no indication that Mars ever had life as we know it. The band around a sun in which life as we know it on Earth is rather narrow and both of Earth's sister planets, Venus and Mars are well outside of that band.

No. No chance I'm afraid. The timeline for Mars that would have had liquid water to support life is too long ago for it to have affected life on this planet. Plus, how would they get here? There is, however, the concept of "seeding". Seeding is when a planet has life, a meteor strikes it and kicks a load of dust into space, the dust carries the bacteria and it lands on earth. Bacteria grows, evolves etc, bingo - we're all martians.

Yep. Ever seen the movie Mission to Mars?

No. not one jot.If you are talking about life on earth in general, rather than gen. hom. sap. arriving ready made from Mars, there is just a tad more plausability; The 'Panspermia' theory. promoted by Fred Hoyle and other, is treated seriously in some quaters, but there is no evidence.

Life may originally have come from Mars. Whatever evidence we have is from meteorites which could only have come from there.

The feeling is sometimes that microbes could have traveelled by a meteorite from mars to earth. these microbes affected dna etc and led to human life.

this url has a theory

Mars never had a chance to substaiin complicated life. It lost its magnetic field eons ago when its molten core cooled. So how can man come from there?
