The universe appears "old", but it is still less than 10,000 years old

[Cyberman]

After spending some time researching why on 'earth' are the 'young earthers' insisting on this minuscule timeframe like 10,000 years, I reached an epiphany; they want to easily dispose of evolutionary models for the origin-of-life which would require eons of time. of course they have to argue that the law of physic have changed, but they being biblically based should know God has stated those laws are fixed throughout the U's existence.

I agree with you as to the YEC's motives and add merely that this 'single-bullet', checkmate approach is misguided in a textbook cart before the horse sense. Evolutionary models for the diversity - not the origin - of life as we see it today do not require aeons of time so much as happen to have taken them to reach the current state. Species evolve over generations; those that take several years to reach reproductive maturity are necessarily going to have longer periods between generations than those reproducing over a shorter timescale, thus evolutionary effects are going to take much longer to become apparent. That's why biologists use fruit flies and bacteria in their experiments rather than humans with their inconveniently long maturation period.
