Sure, here are some scientific discoveries that were discovered way earlier, forgotten, and then rediscovered by someone else:

* **The Pythagorean Theorem:** The Pythagorean Theorem was first discovered by the ancient Babylonians and Egyptians. However, it was not until Pythagoras came along that the theorem was given its name. Pythagoras also proved the theorem mathematically, which made it more widely accepted.

* **The heliocentric model of the solar system:** The heliocentric model of the solar system was first proposed by Aristarchus of Samos in the 3rd century BC. However, his model was not widely accepted until the 16th century, when Nicolaus Copernicus independently rediscovered it.

* **The laws of motion:** The laws of motion were first discovered by Galileo Galilei in the 17th century. However, they were not fully formalized until Isaac Newton came along in the 18th century.

* **The theory of relativity:** The theory of relativity was first proposed by Albert Einstein in the early 20th century. However, it was not until the 1950s that the theory was fully accepted by the scientific community.

These are just a few examples of scientific discoveries that were discovered way earlier, forgotten, and then rediscovered by someone else. There are many other examples, and it is likely that there will be many more in the future.

It is interesting to note that the scientific method is not always a linear process. Sometimes, discoveries are made that are forgotten or ignored, only to be rediscovered later. This can happen for a number of reasons, such as the lack of available technology or the lack of interest in the particular field of study. However, it also shows that the scientific process is not always perfect, and that there is always room for improvement.
