Discovery_DNA and dinasours' history

Discovery: DNA and dinasours' history
A Discovery documentary has reported the following data:
a) A dinasaurs' bone has soft tissue!
- It defiles the general belief that DNA will not survive over 100,000 years. The dinasaur is believed to be over 68,000,000 years.
b) Dinasaurs' DNA may be in the birds.
- Controlled "mutations" have caused a species of bird to have long tail, teeth, and even scales like the dinasaurs.
 
What are the implications?
I propose some changes in the old theories or understandings.
 
1) The dinasaur found is in fact around 100,000 years (or less, e.g. 20,000), not the long number. With the data given in b), we can believe that the mutations do not need so long as previously assumed. Change of the related species are in fact some changes in the DNA rendering (using some genes, and close the other geners.) The time needed for "Evolution" to take its effects are shorter than previously proposed.
 
It can use to explain:
 
1.1 Why so many years have been passed, the Earth is not full of all kinds of animals fossils.
1.2 It can explain why a human footprint is found in the footprint of a dinasaour! Simply they live in the same age, not millions years away.
 
2) The cultures of human kind may be shorter than previously proposed. The so-called old stone age "man" may be just a kind of man caused by mutations. The time span between old stone age to new stone age should be shorter than we think or even the same time! The old stone age man may be just a mutated "group" or indivduals. The human culture starts at most 20,000 years before.
 
Since using the archaeological finds and myths and other stories about the old times, we can reconstruct some pictures in the ancient times, but it seems that we lose the picture before 20,000 years ago.
 
REFLECTION
1) I don't believe in Evolution and think the large time span is wrong. In fact it is also a kind of belief, cannot be scientifically proved. History cannot be tested by science.
2) The historical records and myths put human culture starting in a time around 8,000 to 10,000 BC.
3) The Evolution is impossible to explain the loss of so many species in so long a time in history.
