I once heard a radio show host ask a caller, if it could be proven beyond the shadow of a doubt that the Bible wasn't true and that Jesus wasn't who he claimed he was, if the caller would be willing to accept that information. I remember thinking that I would like to ask the host the same question, turned around, if it could be proven, beyond the shadow of a doubt, that Jesus really was who he claimed to be, would you accept that? Are we willing to believe the evidence? Or do we resist truth or new ideas because of preconceived notions, traditions, or dogma? I see no problem with evidence and the truth. It certainly beats lies.
One scientific challenge young earth creationists have had to address is the starlight-time question.

Toxicologists like myself make a living out of evaluating the impact of chemical exposures and other insults on the health of laboratory animals (we can't test humans after all). Rats and mice, members of the evolutionary order Rodentia, make up a large majority of these experimental animals. Ken Boschert, a veterinarian with Washington University's division of comparative medicine and the operator of a Web site called Net Vet (netvet.wustl.edu/) estimates that 99 percent of experimental animals nowadays are rats and mice, which are small, cheap to feed, and reproduce quickly. Rats and mice are also believed to share a closer evolutionary lineage to humans than other non-primate mammals.
The universe is vast. The Earth seems large, yet when examined on a cosmic scale, it is like a spec of dust, even less than a grain of dust. The sun itself is large enough to hold about one million Earths. And the sun is only an average star in a galaxy containing many, many stars in a universe of many, many galaxies.
