Could there be po­ten­tial life at our near­est ex­o­planet, Prox­ima Cen­tauri b?

yes! The an­swer is yes. life is com­pli­cated, but, at its sim­plest, the po­ten­tial for life is syn­ony­mous with the po­ten­tial for liq­uid water. Wher­ever there is life on Earth, there is water; wher­ever there is water on Earth, there is life. Water ap­pears to be not only nec­es­sary for life, but a good in­di­ca­tion of it as well.

The molec­u­lar struc­ture of water gives it a pos­i­tive side and a neg­a­tive side.

This helps water dis­solve chem­i­cals, group sim­i­larly charged com­pounds and re­main liq­uid through a wider range of tem­per­a­tures. This, and other at­tributes, make water greatly con­ducive to both life and the or­ganic re­ac­tions that gov­ern it.
