Lots of errors there. First, scientists are usually pretty leery of fabricating evidence. If your results can't be reproduced, it can be career-ending for you. And even scientists question the methodology from time to time. Read some Karl Popper or Thomas Kuhn; The Structure of Scientific Revolutions. Not that they can't make mistakes. Both Popper and Kuhn goofed on some things. Popper even came forward and discussed his error.
Perhaps you don't know what "circular reasoning" means. What do you think it means?
YE creationists aren't scientists. Do you have some real examples? Show us from the scientific literature. What do you have?
No. Science can only investigate the physical universe. You shouldn't worship science. It's just a method. Granted, the best method we have for investigating the physical universe, but that's it.
Not all YE creationists are just following fairy tales. Some are making a good faith effort to support their religious ideas with evidence.
Sounds like you don't know the difference between true science and pseudo science.
In true science, everything must be proven with actual evidence, not theoretical non existent evidence as in pseudo science.
We poses the truth and our science is fully documented an proven by irrefutable evidence. There is none of this theoretical nonsense involved.
We have all the evidence from the One who created everything, He told us how everything came into being because He actually did it Himself. So it's up to pseudo scientist to fabricate evidence to try and disprove what God said, all the evidence confirms a YE, there is no fossils older than 6,000 years.
Now just before you go off on a tangent, with your circular reasoning defense. Understand that God created everything, in a fully mature state. Adam was around 30 years old on the day he was created, all the trees were fully mature. The sedimentary rock layers already appeared to be billions of years old, and everything else looked fully mature and old.
So you can't apply your circular reasoning to this equation, and say the sediments on the river bed show millions of years worth of layers. God did that to confuse foolish wise guys.
There's no such thing as a Christian scientist who puts his faith in deluded snake oils salesmen like Darwin. We already poses the truth and no mad scientist has ever come up with any scheme to challenge the truth. All they have managed to do is deceive those who are already blind to the truth, but they can never damage the integrity of God who always has the last laugh.
