Sorry to bump, but I think there are other contestants for extremely large conventional wars. One would be the Red Alert One ww2 which involves 100 million people dying overall, as one would expect from an invasion of continental Europe would be. Another could be from the Earlier ww1 timeline on the alt-history wiki; a Dogger Bank gone wrong turns the Russo-Japanese war to an 11 year conflict claiming over 100 million lives.
My own one would be my expanded ww1 timeline which I never got round to doing but have a couple maps for. It involves Germany enacting the Full Schlieffen plan, resulting in an even bigger trench line across France. To break this stalemate, Germany offers the Spanish Morroco and Gibraltar in exchange for war, which they accept. Later, in 1916, they offer China their former colonies, along with all of former Qing territory, Korea. And Vietnamese vassals and modernisation assistance after the war as a distraction in the Far East, inflicting devastating casualties on the Japanese and Russians, prompting Ango-Russian forces to force Persia and Afghanistan into the Entente. (This latter bit is not in it so far, but came from http://m.youtube.com/watch?v=ctp_2r8XSVk&desktop_uri=/watch?v=ctp_2r8XSVk) Germany as a last resort from American intervention successfully sends the Zimmerman Telegram (more Allied forces are in Asia and Spain) resulting in Mexico attacking Los Angelos, San Diago and Belize City encouraging Colombia (against Panama), Venezuela and Bolivia to join in on the fun against Brazil. The war drags on till well into late 1919, followed by a worse influenza which alone claims over 100 million lives on top of the 80-120 million of the war itself. And you know what's even worse, it results in a worse WW2 with a fascist, blitzkrieging China, a Carlist inquisitionist Spain, a Pan-Hispanic Mexico, an Allied Japan, and an even higher death toll by the time the war finished in 1947, with a few nukes involved near the end.
Also, regarding the debate about Cain and Abel and their lifetimes, there are many explanations for that- either evolutionary compatibility among other hominids through DNA sequencing, the genetic evidence seeming to suggests humans had peak physiques eg heights of 6 foot two average in the distant past and the fact there is little way for one to interpret years differently as unlike day, the word for year in Hebrew is consistent- it couldn't be months as that would mean that people who were grandparents at 34 years would be toddlers. And I won't even get started on other areas.
Otherwise, I could come up with other ways for worse wars if you like
