Could these have formed during the Flood 4500 years ago??
If they were all of that age that would be a very good explanation. The problem is, these old soils can have a wide range of ages. In some cases there are soil layers stacked one on the other spanning many thousands of years, from long before the 4500 years ago date to modern times.
The usual case for soils is a wide range of depositional environments, with some from wind, some from water, some from slides, etc., and they are often cut in areas by subsequent events, such as streams. These layers can be read by sedimentologists, and usually dated pretty well with a combination of radiocarbon and faunal/floral dating.
All of these things that sedimentologists and archaeologists observe would be different if there was one final event such as a global flood. That would have created such a depositional signature that it would have been found easily when geologists first started looking.
