Confession of ignorance when it comes to origins :

More than 30 years of experimentation on the origin of life in the fields of chemical and molecular evolution have led to a better perception of the inmmensity of the problem of the origin of life on earth rather than to its solution . At present all discussions on principal theories and experiments in the field either end in stalemate or in a confession of ignorance .
