at what point did inorganic matter become organic life forms and what caused it?

[Fidel_Castronaut]

this is an awesome question... i thought atoms like hydrogen, oxygen, carbon were the basic atoms of life, other atoms like metallic atoms can not be used for life forms, that would be interesting though to have life forms with metallic atoms

Haemoglobin wouldn't exist without iron, meaning we would either.

In fact metallic elements are crucial to our existence. Without many of the metallic elements on the periodic table, life wouldn't exist. Indeed, the alkaline earth metals are also crucial to our existence too.
