The thing is: Evolution works so well to explain how biology works. So far, no one, especially the Creationists, has come up with an better explanation of how biology works.
"Some "evolutionist" scientific achievements since 1955 –
1955 Salk Polio Vaccine
1961 Crick, Brenner et al discover that three nucleotide bases are needed to code for amino acids, confirming a suggestion by nuclear physicist George Gamow.
Sabin Polio Vaccine 1962
1963 Effective measles vaccine.
About 1964 Har Gobind Khorana and others work out the genetic code.
1969 Arber and Meselson confirm that restriction enzymes cleave DNA.
1969 Rubella vaccine.
1971 Measles, mumps, rubella combination vaccine.
1972 Berg produces the first artificial recombinant DNA molecules.
1973 Boyer and Cohen make the first transgenic organism.
1978 Riggs and Itakura make the first genetically engineered insulin.
1978 Fred. Sanger et al publish the dideoxy chain termination analysis of DNA.
1980 Frank Fenner oversees the eradication of smallpox.
1980 Robert Gallo et al identify the first human retrovirus.
1983 Recombinant insulin placed on market.
1988 Kary Mullis et al publish the polymerase chain reaction.

Your turn, what have Creationists done that matches that impressive record of achievement?
Matthew 7:16 , look it up, it applies here.
What is useful about Creationism?
"Young Earth creationist leaders are careful to do no actual science. This is indicated by the scarcity of patents with their names as inventors in any field of biotechnology or medical research. They never discover anything, they never invent anything. By contrast, genuine scientists in these fields have tens of thousands of patents spread across a wide range of topics.
Young Earth creationist leaders only preach to the public, they know if they tried to preach to the biotechnology, agrochemical, pharmaceutical, oil and mining industries among others they would be hurled out on their ears.
All young Earth creationists leaders are completely deluded or fraudulent and their followers have the insane idea that virtually all astronomers, cosmologists, planetary scientists, geologists, physicists, chemists, biologists etc in every country of the world are conspiring against a minority of mostly American sects." - Brigalow Bloke
