the central problem is that Indo-European is too old for genesis.
If you mean the Hebrew bible, yes this is a late comer in the ancient world. However, I find it mysterious that Genesis depicts the history of modern man [speech endowed kind] with remarkable credibility. There is no other document which lists names, dates, places and events dating 5000 to 6000 years which matches Genesis. I know of no name, nation, city, king, monument, etc - older than that depicted in Genesis - there is no history beyond 6000.
