You have been visiting too many lying creationist web sites.
Evolution has been tested by various means ever since Darwin proposed his theory, and it has always come through with flying colors. Here are some examples in which the theory of evolution has been tested.

As to your arguments about the flood, they are nothing but creationist nonsensical BS.
According to the creationist argument, all species (or basic kinds--whatever), living and extinct, were created at the same time and the fossil record was laid down by the biblical flood.
In the first place, if it had occurred, the biblical flood would not have left all of the different kinds of layered strata that exist, many of which are interwoven with entirely different methods of deposition, not all of them water related. All of those different kinds of layers could have been laid down only by widely different conditions over a great length of time.
Furthermore, if the biblical flood had occurred, you would find fossils of the approximately 5,000 present-day species of mammals, including humans, and of the approximately 10,000 present-day species of birds, mixed in with the fossils of, for example, dinosaurs. You do not and will never find such a mixture. That is because they are separated in time by more than 60 million years and the fossil record reflects that fact. The only fossils of mammals and birds that are found in the same strata as dinosaurs are early types quite unlike anything that exists today (even if you consider the "kinds" that creationists refer to as the source of present-day mammals and birds). And you will also not find those fossils of present-day mammals and birds in the same strata with trilobites, or of numerous other early types of animals.
In the Cambrian strata, which was laid down long before the time of the dinosaurs, you will find the initial appearance of most of the phyla, but they will be only very primitive species--none of which exist today--belonging to those phyla. You will not find one single amphibian, reptile, dinosaur, bird, mammal, or teleost fish.
And that scenario even continues after the demise of the dinosaurs. As you progress through the strata you will find new forms, but still nothing like what you would find today until you get to relatively young strata. There are numerous strata which show that mammals became predominate for several tens of millions of years on up to today. But the strata that was laid down during the first half of that time contains a large number of fossils of mammals quite unlike anything that exists today, and again, none of the fossils are of present-day mammals, including humans, and present-day birds. As those strata get progressively younger, you begin to see more and more fossils of mammals and birds that are similar to the present-day species. That includes hominid fossils, which are present only in the strata laid down in the past few million years. Hominid fossils are totally absent in the vast number of earlier fossil-containing strata.
Note the appearance of types of organisms over time in these tables:

http://en.wikipedia.org/wiki/Geologic_time_scale#Table_of_geologic_time
Thus, if you look at the geological strata, you will find a changing representation of species through the oldest to the youngest strata, and those changes reflect an evolutionary process. That is not what you would find if the fossil record had been laid down by a flood such as that described in the Bible. But it is what would be expected in an evolutionary scenario.
And the fossil therefore is another verifiable test of evolutionary theory.
