though I would catagorically deny the existrence of any of the made up charachters in the Jewish Book of Faery Tales ... there is evidence in the sumarian cuniform, suggesting just that.
IF and I did say if, the cuniforms are correct, whatever "beings" were here, certainly had the ability to travel the planets, it becomes by extension possible that they had stem cell technology in their bag of tricks. Stem Cell Tech is in infancy now but its use can help humans to extend their life. They suggest about 140 yrs with present tech.
