In the early generations man didn't have a choice. Cain married the only gals around - his siblings. Abraham also lived long before Moses, who wrote Deuteronomy and Leviticus.
After Moses, no, not a good idea to marry your sister.
Abraham married his sister and God blessed the union- Genesis 20:11-12 - She really is my sister, the daughter of my father though not of my mother; and she became my wife
- Genesis 17:16 - I will bless her so that she will be the mother of nations
