Scientists estimate the Earth is 4.54 billion years old (with an error margin of about 50 million years). [1]
Researchers use a branch of science called radiometric dating to determine this age. Because the Earth's crust is constantly recycling through plate tectonics, scientists instead rely on: [1, 2, 3, 4]
Meteorites: These space rocks are leftover building blocks from the early solar system. Dating them helps pinpoint the formation time of the planets.
Lunar Samples: Rocks brought back from the Moon (which lacks plate tectonics) show it formed around the same time.
Zircons: Some of the oldest known minerals on Earth have been dated to roughly 4.4 billion years old. [1, 2, 3, 4, 5]
If you are curious about the methods used to determine this, let me know:

I feel like it changes, that it used to be 3.9 billion. Now 4.5. But the 4 Gospels, Lazarus was dead 4 days, Matthew 4:4. But I'm the crazy one. Man does not live by bread alone but by every word that proceedeth from the mouth of God! Without self-discipline human beings are just primates, often very backwards ones!
Jesus whipped 39 times, car hit me on my bike at 12 was going 39, met that girl in the psych hospital after I was put in a Gas Chamber Extermination Camp and witnessed a man in a wheelchair die on the property! Slept 4 days and nights in that hospital! Evansville, Indiana is deader than Sodom!
