Might as well...

Others like Cid might not make it as far as reddit.

Boats.
Without them, there would have been very little long-distance travel or trade during the late Neolithic and early bronze ages.
Reduced trade and travel would have meant less innovation in fields such as agriculture and metallurgy.
Without boats, we may well have stayed in the stone age.
