Explanation:

Radioactive dating techniques, such as uranium - lead dating, have been used to date rocks. The oldest rocks on Earth (zircon crystals) and samples from the Moon (brought back by Apollo missions) have been dated to approximately 4.5 billion years. The age of 6,000 years is based on a misinterpretation of religious texts (young - Earth creationist view) and has no scientific basis. 100 million years and 2 million years are much too young for the Earth and Moon. And we do have scientific methods (like radioactive dating) to measure the age of old objects.

Answer:

About 4.5 billion years
