You are correct! The age of man has no bearing on the age of the earth! So if you want to get into specifics about the age of the earth here goes.
If you are familiar with radio-isotopes you will know that there are several such as neptunium that have very short lived half lives. Neptunium is an isotope of Uranium with a half life of 2 million years. It takes 10 half lives for an element to completly disapear. so if the earth were less than 20 million years there should be abundant amounts of neptunium in the earths crust as there is Uranium. However, there is only trace amounts found only in places that produce uranium meaning that the earth is at least 20 million years old. When you combine that with other short lived isotopes you can extrapolate the age of the earth to about 4.5 billion years old.
My field of expertise is in Petroleum geology and engineering. I have studied this for a long time. I have found mulosk fossils called foramformas at 17,000' deep in the earth in a water depth of 2,000' in the Gulf of Mexico. This amount of sedimentation takes millions and millions of years to happen not 6,000 years as some want us to think.
This however does not negate the scripture but only our interpretation. If science discovers something that contradicts what we believe scripture says, it is our interpretation that needs adjusting not scripture being wrong nor science being wrong.
