Martians on the moon
According to Houtkooper there is no reason why one should limit the travel and preservation of microorganisms from the Earth to the Moon. He says that if life existed on Mars, a similar process may occur between Mars and Moon. There may be several Martian substances that are waiting being discovered in the dark and deep parts of the Moon’s craters.
The origination of ancient life can be determined, if these were found on the Moon’s surface. Microorganisms feature isotopic signs that are like biological determinants, which show their birthplace. We could easily and accurately determine if the conserved life forms have originated from the Earth.
The same may be true for Mars, which is possible after the several years of scientific research of the red Planet has revealed plenty of information on the planet’s condition and history. In addition, if we cannot determine the isotopic sign, then another intriguing possibility is the origination of these microbes from other more exotic planets.
