>Two different plants can natuarally cross pollenate and create a new plant type.

however, humans encourage "unnatural" crossbreedings. many of our food plants today would never naturally occur - in nature the plants that will produce the most progeny are the survivors but humans encourage traits that will produce the most and best quality food. nature and man have different ends, and thus a different means has developed.

>But flies and fish can not naturally produce anything with a tomato or any other vegetation.

obiviously true.

i see what point you were trying to make and i probably cant persuade you otherwise if you feel that way about it so ill agree to disagree.
