According to one study, Mars may have lived in life earlier than Earth



A new study suggests that life on Mars could have existed hundreds of millions of years before its creation on Earth.

The Red Planet may have been around 4.48 billion years ago, "The inhibition of meteorites has stopped hitting the planet," says the study, and it is possible that life was 4.2 to 3, As the lead author of the study, Desmond Moser, pointed out, could have thrived 5 billion years ago. "Huge meteorite impacts on Mars from 4.2 to 3.5 billion years ago could actually have sped up the release of early waters from inside the city Planets and formed the basis for life-forming reactions, "Moser said in a statement," This work can show good locations where samples from Mars can be returned. "

"[Ninety-seven percent] grains show weak to no shock metamorphic features and no thermal overprints due to shock-induced melting," the study's summary states. "By contrast, about 80 [percent] of the investigated grains of the bombarded earth crust and moon have such features, so the gigantic impact that Mars' hemispherical dichotomy provoked must have occurred before more than 4.48 gyr, and no later catastrophic ones Bombardment.

It is generally believed that Mars formed about 4.6 billion years ago and Earth soon became after about 60 million years later. It is generally believed that life first appeared on Earth about 3.5 billion years ago.

The study was published earlier this week in the journal Nature Geoscience.
