how come a lot of people are lactose intolerant if everyone started off by drinking milk as a baby?

Not sure if anyone mentioned beta casein here? Cows produce a different beta casein then humans and its harder for many to digest. Animals like goats, donkeys and camels produce the same beta casein (A2) as humans and it’s easier for us to digest their dairy. There are now many small cow farms producing cows with A2 beta casein through genetic processes so that customers will be able to buy their cow milk products still.
