For example, if you start off with 1000 radioactive nuclei with a half-life of 10 days, you would have 500 left after 10 days; you would have 250 left after 20 days (2 half-lives); and so on.The half-life is always the same regardless of how many nuclei you have left, and this very useful property lies at the heart of radiocarbon dating. The graph below shows the decay curve (you may recognize it as an exponential decay) and it shows the amount, or percent, of carbon-14 remaining.
By measuring the amount of carbon-14 left in the organism, it's possible to work out how old it is.
This technique works well for materials up to around 50,000 years old.
However, the origin of the universe and the origin of life cannot be tested or observed.
Both creation and evolution are faith-based systems in regards to origins.
Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960.
The halflife of carbon 14 is 5730 ± 30 years, and the method of dating lies in trying to determine how much carbon 14 (the radioactive isotope of carbon) is present in the artifact and comparing it to levels currently present in the atmosphere.
After it forms, carbon-14 naturally decomposes, with a half-life of 5,730 years, through beta-particle decay.
For the record, a beta-particle is a specific type of nuclear decay. Image 1 shows carbon-14 production by high energy neutrons hitting nitrogen-14 atoms, while in Image 2, carbon-14 naturally decomposes through beta-particle production.
Scientists who advocate evolution are rejecting a plausible theory of origins without even honestly examining its merits, because it does not fit their illogically narrow definition of “science.” If creation is true, then there is a Creator to whom we are accountable. Evolution gives atheists a basis for explaining how life exists apart from a Creator God. event=AFF&p=1011693& Creation In The 21st Century - Planet Earth Is Special 1 of 3

Of Course Evolutionary scientists mock creation and/or intelligent design as unscientific and not worthy of scientific examination.
