Things, all through history, have not been made because they could (or could not) but because there was an immediate benefit or a need for it.
Speculating on all that "could have happened beyond what is demonstrable" is an exercise for those without any meaningful tasks to occupy themselves with.I don't fall in that category.
Thats exactly where Im going. We found something like watch on ship. So I thought why not.
Also how do you know that there wasnt long distance communications?
Roman artifacts in Vietnam and Japan.
Greeks who went northen of UK.
Phoenicians and Chartageans...
I dont know but I learnt that there were big distance travels. Also can provide more info. It depends what do you found big distance travels.
