It only speaks of ways in which DNA is damaged in living cells - (which fossils are clearly not).

In fact, it mentions an experiment in which DNA from a sample millions of years old was extracted successfully.

Furthermore, with the experiment you claim he cites that shows a "sample millions of years old was extracted successfully", while acknowledging the authors' care in doing the experiment, consistent with his scepticism over DNA being extracted from fossils millions of years old Lindahl casts doubt on their findings (p. Lindahl says that the DNA not rejected as contamination, was "somewhat arbitrarily assigned as being representative of the [termite] fossil". Lindahl: "It will now be important to assess the reproducibility of such findings." He then goes on to criticize another claim of DNA found in a magnolia leaf said to be 20 million years old.

If what you claim in point 16 about oil being formed quickly then why don't you start making it and prove your point..i'll tell you why because you can't.

If you read the linked papers you would find that the claims come from mainstream peer-reviewed research; we did not make this up.

You would also have seen that with the main paper cited about oil, simulating assumed natural conditions, it took to produce oil, which would hardly be an economically viable way of producing oil to sell.

Furthermore, in most cases I am citing work by specialists in their fields.

Regarding your claim about Lindahl's paper that I cited, note the introductory summary statement to the paper: "The spontaneous decay of DNA is likely to be a major factor in mutagenesis, carcinogenesis and ageing, and also , under the heading "Ancient DNA" (p.713), he comments on what it means for the recovery of DNA from fossils: "Thus, in connection with favourable preservation conditions, it seems feasible that useful DNA sequences tens of thousands of years old could be recovered, particularly if the fossil has been retained at low temperature." He suggests that partial dehydration of DNA, as in bacterial spores, could extend this ("further increased stabilization").

Someone DID work out that when seeds are planted, sprouts grow, and they would produce something edible.However, he says that air-dried tissues remain partly hydrated and susceptible to decay and that dessicated DNA, where the water in the grooves of the DNA double helix is removed, is susceptible to accelerated damage.So, I stand by my characterization of this work that it argues against DNA lasting for millions of years.Additionally, I followed the link for the first claim, that the presence of DNA in 'ancient samples' refuted the samples' supposed age.
