Kuki amacupa yicyatsi kibisi?

Amateka ya byeri ni maremare. Inzoga yambere yagaragaye ahagana 3000 mbere ya Yesu. Yakozwe n'uwakozwe na Semite mu Buperesi. Muri kiriya gihe, inzoga ntiyigeze ibeshya, kereka ubusa. Ni kandi iterambere rihoraho ryamateka avuga ko hagati yikinyejana cya 19, inzoga yatangiye kugurishwa mumacupa yikirahure.
Kuva mu ntangiriro, abantu bagaragaza ko ikirahuri ari icyatsi - ikirahure cyose. Kurugero, amacupa yinkingi, ya paste amacupa, ndetse na idirishya ni icyatsi, kandi, byumvikane, amacupa yinzoga.
Kuberako inzira yambere yo gukora ibirahuri idakuze, byari bigoye gukuraho umwanda nka onterede ya Eons mubikoresho fatizo, ikirahuri kinini muricyo gihe cyari icyatsi.
Birumvikana ko ibihe bihora biteza imbere, kandi inzira yo gukora ibirahuri nayo yazamutse. Iyo umwanda mubirahure ushobora kuvaho burundu, icupa rya byeri riracyari icyatsi. Kubera iki? Ni ukubera ko inzira yo gukuraho burundu ni ihenze cyane, kandi ikintu cyakozwe nkinkoko yinzoga biragaragara ko bidakwiriye ikiguzi kinini. Kandi byingenzi cyane, amacupa yicyatsi yabonetse kugirango akemure neza.
