Explanation:
Space is called as Brahman because it is the greatest in the universe. But it cannot be God for philosophers, athough it is God for all atheists and scientists. The reason is that space has the single defect that it cannot wish to create the universe as said in the Veda. In the Veda, it is said that God wished to create the universe. By this single point, all the merits of the space are discraded in the Brahma Sutra (Ikshaternaashabdam). Therefore, space is called as Brahman in the sense that it is the greatest among all the items of creation. Using the word Brahman here does not mean that space is God.
