This one is funny:

Me neither. Maybe you read too much creationist stuff to know what's going on in geology?

it's just that Geologists are always talking about this or that layer as being formed in a shallow sea or a lake and so on and so forth.
I'm not too sure why you mention this.
Some "layers" are formed by volcanic action in Hawaii. Some "layers" are formed by volcanic action in the Great Rift Valley.
Some "layers" are formed on deltas emptying in the Mediterranean. Some "layers" are formed on deltas emptying in Lake Victoria.
Some "layers" are formed in the deepest parts of lakes. Some "layers" are formed in the shallowest parts of lakes.
Some "layers" are formed at MOR's. Some "layers" are formed on beaches.
Some "layers" are formed in the Sahara. Some "layers" are formed on Antarctica due to glaciers. Some "layers" are formed on Antarctica due to thick ice covers.
Some "layers" are formed in the Kalahari desert due to wind. Some layers are formed in the Kalahari desert due to rivers evaporating.
Some "layers" are formed due to floods when rains fall on the highest peaks of the Drakensberg and the mountains get eroded.
The Himalayas are growing at around 5 mm a year.
All of these happening at the same time.
In geology we can distinguish between those settings. The method is quite simple. The present is the key to the past.
