Why??? Easy. Pick any animal. Now ask the evolutionist what animal this evolved from. Then look for any or all transitional creatures, the "in between" ones. Not ONE can be found for ANY animal. Period. We have fish and we have land animals. According to the evolutionists the land mammals evolved from sea creatures by developing legs; therefore, there should today be all kinds of transitional creatures still evolving, i.e., fish with nubs for legs, fish wish short little legs, fish with half legs, fish with full legs, land animals with fins, small fins, ad nasuem. But, no, we have fish, and we have land animals. When you compare what the evolutionists world would be with God's creation doesn't it make you appreciate Him all the more? Can you imagine a world in which every "person" was at some fuzzy stage of evolution between being a man and a monkey??? What a mess! I've said it before; I'll say it again. The more you think about the theory of evolution the funnier it gets. :-)

It seems you have misunderstood the concept of evolution. You think species are static but that's not the case. Changes occur only in the individual animal (the offspring is always a little bit different from its parents) but as long as a population stays together these changes are 'shared', i.e. the gene pool of this population mixes through the act of procreation. That's why this population _drifts_ away from it's original "position", i.e. this population is different from its predecessor several generations ago.
Now it can happen that a population gets split. That means the genetical changes in the individuals of these two populations are no longer 'shared' and as a result these two populations drift appart. Of course they also drift away from their original "position". If after several generations you take an individual from each of these populations and you cannot interbreed them then you can say for sure that you have two distinct species (notabene they live at the same time).
You expect that a population remains unchanged over a long period of time. This can happen (though slight changes always occur) if the environmental conditions don't change. But this is a very, very, very rare phenomenon. It's an exception rather than a rule. (A good example for this would be the coelacant, though slight changes happent even to him over the millions of years).
Therefore intermediates exist only as fossils if they're preserved (and that again is rather an exception than a rule). A cousin isn't an intermediate between you and your great-great-grandfather even if he may look just the same as this common ancestor (intermediates lie along the time axis).

Correct.

therefore, there should today be all kinds of transitional creatures still evolving, i.e., fish with nubs for legs, fish wish short little legs, fish with half legs, fish with full legs, land animals with fins, small fins, ad nasuem.

Incorrect. The environment in which the original fish (and other creatures) became amphibious and then land dwellers no longer exists. Now there is a great deal of competition from existing amphibians and land dwellers, so there's little opportunity or pressure for sea creatures to become land creatures.
