Is there positive proof that the earth is between 4.5 and 4.6 billion years old?

Answer 1

The scientific evidence for the age of the Earth at roughly 4.6 billion years is overwhelming from radiometric dating of chondritic meteroites and samples of rock from the moon. It is a generally accepted fact based on scientific methods. Efforts to debase the scientific proof are based on religious and spiritual biases. There is no religious or spiritual bias in science. Science is based on testable, repeatable scientific experimentation and is the basis of modern medical achievements, advancing technologies, agricultural production, and modern conveniences. One may question whether the fruits of science are good or bad, but science itself is the pursuit of truth. Testable truth. If there were overwhelming truth that the Earth was considerably younger, the vast majority of Earth scientists would accept that. But it's just not so. However, the evidence for a younger earth exists as well, and should be taken into consideration. Evidence includes comets, the amount of salt in the sea, and erosion.

Many knowledgeable experts disagree on the issue; many earth scientists do indeed accept a younger earth, and many do not.

Religion really is not an issue. To most religions it does not matter weather or not the earth is young or old. Many religious scientists disagree on this topic. Science is indeed about trying to find truth. When evidence points both ways, and leading scientists disagree, you have to make up your own mind by looking at the evidence closely and evaluating differing arguments.
