It is difficult to determine exactly which language early man spoke, as there is no written record from that time. However, linguists believe that early humans likely communicated through a primitive form of language, consisting of gestures, sounds, and possibly even some proto-words. There is evidence to suggest that early humans had the ability to use language to some extent, but the specific details are largely unknown.

It depends. Some churches already believe that man is subject to evolution, but others strictly believe evolution is false and are unlikely to change their thoughts or beliefs at all
