Abraham was an important figure of Israel, but also within the Christian writings. How do we know he really lived?
Abraham’s birthplace and hometown existed. The Bible says that Abraham was born in Ur. Ur’s ruins were found in Mesopotamia, southern Iraq. Excavations have shown Ur to be a trade city around 2000 BC. The book of Genesis says that Abraham's father Terah moving his family to Haran, a city in the northwestern portion of Mesopotamia. Excavations have proven that Haran was abandoned around 1800 BC.
There is evidence placing Abraham in these locations at the time stated. A discovery made in 1975 in the ancient city of Ebla yielded 17,000 clay tablets. Ebla was a city in what is now Syria, in the region between Mesopotamia and Palestine. On these tablets, a number of names are recorded, including Isaac, Jacob, and Abraham, as well as the names of Abraham's father, grandfather and great grandfather, Terah, Nahor and Serug. These names are also known from other sources in Northwest Mesopotamia in both Babylonian and Old Assyrian texts.
