What evidence supports the hypothesis that Earth is 4.6 billion years?

Among other things, rocks have been found that are over 4 billion years old. The age of such rocks is determined by radioactive dating. Note that this is not "a" method, but perhaps 40 different methods (depending on the isotopes involved), which complement one another.
The exact age of the Earth is harder to determine exactly; but basically, it must be at least as old as the oldest rocks found.

What pieces of evidence supports the theory that the Earth's interior is composed of different elements than those prominent in the crust?
the difference in the Earth's average density from its expected value
How long has life been on earth?
The best guess is somewhere between 3.5 and 4 billion years, with the earliest clear fossil evidence being about 3.4 billion years old.
What evidence supports the idea that the earth is neither growing nor shrinking size?

What is Alfred Wegener's hypothesis about the continents?
Alfred's hypothesis was that all the continents were a big land mass which he called Pangaea because if you see a world map it is like a jigsaw puzzle and other evidence is that some animal fossils were on other continents. Also the same rock range was found on different continents.

What happened 3.8 billion year ago?

What evidence indicates that our solar system is about 4.5 billion years?
The main evidence is from radioactive materials on Earth, as well as their by-products.
How is the hypothesis about Earth's earliest life forms consistent with fossil evidence?
I know you have a textbook so use it
How many years did earth exist before there was evidence of life on?
About 10 billion years
