The science that allows me to send data over the internet and use a gps is real science. The science that says the earth is 4.5 billion years old is psuedoscience.
It's the same science. The EXACT same science. You simply don't understand it.
One example is Mt. St Helens we know it errupted in 1980 and that is the date of the lava, but when sent to be dated at the labratory it comes back dated 2.8 million years old.
Yep. I am well aware of that. The lab the samples were sent it to was specifically and only designed to test the ages of things 2+ million years old. Anything not at least that old and their results would be in error, unless, of course, you have another example you want to cite?
As an analogy, you might as well say weighing things doesn't work because the scale at the gym didn't move when you put a feather on it. You would be wrong in both your choice of tool as well as the analysis.
