For centuries people have speculated about the possibility of life on Mars due to the planet's proximity and similarity to Earth. Although there has been much speculation, to date there has never been any proof of life existing on Mars. However, cumulative evidence is now building that Mars once was habitable.
Serious searches for evidence of life began in the 19th century, and they continue today via telescopic investigations and landed missions. While early work focused on phenomenology and bordered on fantasy, modern scientific inquiry has emphasized the search for water, chemical biosignatures in the soil and rocks at the planet's surface, and biomarker gases in the atmosphere.
Mars is of particular interest for the study of the origins of life because of its similarity to the early Earth. This is especially so since Mars has a cold climate and lacks plate tectonics or continental drift, so it has remained almost unchanged since the end of the Hesperian period. At least two thirds of Mars's surface is more than 3.5 billion years old, and Mars may thus hold the best record of the prebiotic conditions leading to abiogenesis, even if life does not or has never existed there. It remains an open question whether life currently exists on Mars or has existed there in the past, and fictional Martians have been a recurring feature of popular entertainment of the 20th and 21st centuries.

Take my hand, I don't know the way,
Nor the way back.
I need a guide who knows, who's seen the edge of the world
And lived to tell the tale.
Once in a while
It's time to let go again
Everythings going to change
Life on Mars, as we've known it.
Yesterday and today, and forever is changed by Your love
Theories gone haywire, assumptions dismatled
As history unwinds and our future is changed, and our future is changed
"There's 8 colours in the rainbow, the moon's just a story,
Evolution got beaten by natural selection"
Now tell me the truth,
Now tell me the truth
