Do geologists and archeologists find any signs that once Israel and Kashmir were together as just one piece of land?

Answer 1

The answer is no. I think what you're getting at the idea that Kashmir is somehow related to the lost tribes of Israel, which is one of a number of myths and conspiracy theories surrounding lost tribes. Both Israel and Kashmir are technically in Asia, so they are a connected landmass in that regard, but they are as close today as they have ever been, which is to say not very.
