Absolute and relative dating methods
A single observation which proves beyond doubt that the earth has been in existence for less than, say, 1 billion years would greatly weaken the arguments in favor of evolution.
There simply would not have been sufficient time for all of the natural geological and biological processes to produce the complexities of the present world.
Thus, the full theory cannot be demonstrated in the laboratory.
Processes like the rise of mountains and erosion are simply too slow to be observed during one person's lifetime. species evolution of fruit flies in the laboratory and of Tilapia fish in East African lakes) have been observed.
It is impossible to prove that the theory of evolution is absolutely true.
Scientists are sometimes able to estimate the age of an object by using two unrelated methods.
According to about 99.85% of America's earth and life scientists, the world did coalesce many billions of years ago.
Species of life have evolved and died out over billions of years, leaving behind fossils in rock layers which demonstrate the gradual development of simple forms of life into more complex forms.
Since the book of Genesis clearly describes that God created the universe, then it must be true. The Answers-In-Genesis web site explains this clearly in their statement of faith, Section D, sub-section vi: "By definition, no apparent, perceived, or claimed evidence in any field, including history and chronology, can be valid if it contradicts the Scriptural record." Thus, if some observation, some fossil, some measurement, or some theory seems to supports the theory of evolution, then it is automatically false and is to be rejected.
There is no possibility that significant numbers of believers in creation science will accept the validity of any evidence in the future that contradicts the Bible.However most have been shown to be pious forgeries created by some very enthusiastic and devout believers.
