How did they think it came into existence? Divine creation? Alien

The force of necessity.

I don't know what 'they' think, but there appear to be neurons in monkey
cortex that specialise in detecting behaviours, either in self or in
others and that feed the input areas of the basal ganglia. This sets up
a mechanism for learning the values of behaviours by imitation. One of
the regions that does this becomes a speech area in humans. That is,
human speech appears to have originated in metaphorical signalling.

Also, audible signals are adaptive for grassland foragers, as they can
be used to communicate at longer distances than gestures.
