Einstein was a great physicist. His theory of relativity and quantum mechanics had a profound impact on modern physics and astronomy. However, he didn't make a prophecy about the destruction of the Earth. Some science fiction novels and movies may have scenes where Einstein predicted the destruction of the earth, but this is just a fictional plot with no scientific basis. In reality, scientists generally believed that the Earth was facing various environmental and climate problems, such as climate change, natural disasters, resource depletion, and so on. These problems might have a major impact on the future development of the Earth. Therefore, we need to take proactive measures to solve these problems to ensure the future prosperity of the earth and the survival of mankind.
