Answer:
since the babylonians are said to have invented the wheel, there are many other things that wouldnt have not come into existence. either that, or they would have come much later.. but it would have also been a very tough few centuries.
the invention of the wheel led to things like plows. at the time, they were the main and only way to till the land, other than by hand. this means no agriculture, thus no food.
there was also transportation. trading, imports, and transporting masses of people would have been impossible by just foot.
the babylonians also developed eloped the concept of time. night and day cycles, weeks, months, years, etc were mostly created by the them (they were later refined as calendars popped into the timeline). along with this, babylonians discovered stars, and began the study of astrology and horoscopes.
(i hate them for this next one but oh well-)
the babylonians also developed geometry in order to move objects and calculate stable structures. this also helped them track moving objects and how far something would move, (ex, flipping a square sideways and keeping ondge on the ground) and where it would land. they already has knowledge about arithmetic and quadratic equations so this was just a step forward in the world of mathematics
there are actually a lot more, but these are the big ones
if you would like anymore, let me know!
hope this helps :P
