Why cant carbon-14 be used to date material that is older than 75000 years?

Carbon has a half life of 5730 years. That means that after 5730 years there'll only be half the amount left. After about 11500 there will be a quarter of the original. After 75000 years there will be about 0.0001 of the original sample which is too small to date accurately?

Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Too little carbon-14 remains after 50,000 years
What is modern materials?
A modern material is not smart as it dose not react to its surroundings but it is a new material that has been created with in the last 50 years.
What material was squeezed over millions of years to form coal?
trees
How does coal form and what is it made from?
Coal is formed from buried vegetation over 300 million years ago. The material formed is called peat. the earth structure changes and deposits of sand and other material are dropped on the peat, putting a lot of pressure and temperature on the material squeezing out water from the material which then gives yield to coal.
Where do the dissolved material of caves go?
Caves are usually some form of limestone. The stone is VERY slowly dissolved by water, and the dissolved material leaves with the draining water. Typically this takes millions of years.
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
Yes, but the dating is only off a little (500 years or so).
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.

Why can't carbon 14 be used to date material that is older than 75000 years?
The half-life of carbon is roughly 6000 years. That means that every 6000 years, the amount of Carbon halves. Therefore, in a million years, the amount of carbon-14 would be so low that it would be extremely difficult to determine the exact age of the shell. So radioactive elements of longer half-lives, such as Uranium-238(half-life of 4.9 billion years) are used to date older objects.

Which isotope is useful for dating wood and charcoal that is less than 75000 years old?
carbon- 14
Which isotope is useful for dating wood and charcoal that is less than about 75000 years old?
Carbon-14 is the isotope commonly used for dating wood and charcoal less than about 75,000 years old. This isotope is useful because plants take in carbon-14 while they are alive, and it decays at a known rate after the plant dies, allowing for accurate dating.
