Yes it is quite possible but some specific clades of R-Y934 because some others are Scythians. R-L657 can also be Arabic but mostly found in Arabian peninsula. Another clade in Levant area is R-CTS6 in which belong the Levites Jews! Really interesting how many indoeuropean subclades there are in so many different Asian peoples.
Turns out I'm I-L233, some Western Variant of I2a Haplogroup.
According to 23&me, my Y-haplogroup is I-L38 which is an I2a2 sub variant. Whats really interesting is the haplogroup seems to be a rare surviving, pre-neolithic west hunter gatherer haplogroup that's most common in the Hartz mountains of North-central Germany. This makes sense, sense my direct paternal ancestors are of German descent. Either way, it's cool to know my fore-fathers have been in europe sense the beginning.

??? I'm not sure if you're joking or not, but if you're not, it should be known that just because the West hunter gatherers had dark skin doesn't make them black, as they had Caucasoid features & blue eyes. Although I'm pretty sure you're joking... I've never been one to pick up sarcasm to well.
