RÍO MARCIANO SALVAJE el rover perseverance DESCUBRE AGUA EN MARTE

Why to think that in Mars still there is life if there were life before? Permit me to make it simple: Mars surface receives a lot of cosmic rays (gamma, X alpha and a lot of various rays) cosmic rays disband the hydrogen bands that joins the genes of any DNA, therefore, if disbanded, they are turned into its simple elements and therefore, life ends. Any planet that cannot have any protection against cosmic rays, there is no life yet there could be water. But water turns into a different liquefied substance, as well water absolves the cosmic rays and any living organism within it, the just said happens then. Well, if water is deep enough, there is a different story. It is like a, b, c, is followed by d and other letters. That is basic physics and chemistry as well as grammar. Been a Physicist or Chemist, is like knowing that the multiplication table of two, its first multiplication is 2 times cero equal 0 or any number multiplied by 0 is equal cero. No? So, does an engineer know that? My advice, tell what a person is not, is stupid. It is easily known by smart people. Cheat not in the internet.
