"By the way, Noah just carried animals. What happened to all the plants?"
Hmmm...let's see...
Ah! Throught the miracle of microevolution, the land plants evolved into aquatic plants within minutes of being flooded. Then, when the flood receded, they evolved back into land plants, in plenty of time for the animals to eat them. But, you see, that was micro-evolution, and that's OK. It happens much faster than macro-evolution, and they were still plants, so they were the same "kind." Yeah...that's the ticket.
There is an explanation for everything...just ask...
Chapter and verse cited on request...
Their seeds were stored inside the animals.
Noah's oak is still sitting on the side of mount arafat but the mean ol' turks won't let us climb up there and have a look at it.
And 20,000,000+ insect species, all the different microscopic forms of life, fresh/saltwater fish and marine life in general...
Excerpts:
"Dendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree ring patterns"
...
"Fully anchored chronologies which extend back more than 10000 years exist for river oak trees from South Germany (from the Main and Rhine rivers). A fully anchored chronology which extends back 8500 years exists for the bristlecone pine in the southwest US (White Mountains of California)."
More than 10,000 years back!
More than 10,000 years back is right! But some minor corrections to your post (this is one of my major fields of study). Dendrochronology, or tree-ring dating, is a separate field of study unrelated to Carbon-14 dating.
The tree rings are used to calibrate the radiocarbon dates--the method involves finding a tree ring, for example, 9950 years ago and Carbon-14 dating that specific ring, then creating a correction factor. The current calibration curve, based on bristlecone pines, is about 11,600 years. There are others, based on other data, extending back over 20,000 years.
But I still haven't heard an answer to my original question (not to MHalblaub): why is the Carbon-14 date of 7140 BP which recently received in error?
