Base 12 was used in ancient Egypt. You can count to twelve on one hand, using your thumb to move on each finger joint (four fingers, each with three joints). Arguably, base 12 and base 60 make more "sense" than base 10, because you can count to 12 on the one hand and keep track of five groups of …

The Short Answer

Base 12 was used in ancient Egypt. You can count to twelve on one hand, using your thumb to move on each finger joint (four fingers, each with three joints).

Some have argued that this using 12 carried forward directly, some argue that it developed independently in lots of different places, which makes sense to me because it works really well.
