There is some scientific evidence that some meteorites found on our planet actually came from Mars. To prove this, experts used the radiometric dating method.

Radiometric dating, similar to radiocarbon dating, helps scientists determine the age of rocks. When using this method, experts study the ratio of radioactive isotopes in meteorites. The isotopes themselves decay at a certain rate, so by comparing their rates it is possible to determine the time elapsed since the meteorite was formed or last heated.

Most meteorites found on Earth are about 4.56 billion years old. This is because meteorites are formed from asteroids that were formed during the formation of the Solar System.

They also found that Martian meteorites have an isotopic composition that corresponds to Martian rocks. Some of these meteorites contained gases whose composition exactly corresponded to the composition of the atmosphere of the Red Planet.

But how did these pieces of Mars get to Earth in the first place? According to scientists, this may have happened because an asteroid or comet hit Mars quite strongly. Few such fragments may have been launched into space and subsequently collided with Earth.
