From book "Atheism Delusion" by Ahmed al-Hasan a.s. - Pages 132 and 133: "The religious texts not only agree with biology and modern science, but they have also mentioned concious life forms, some of which are known today through fossils, meaning the human-like beings like some type of Homo Erectus, Homo Sapiens and the Neanderthal. These texts have stated that human like beings existed before humans, and some of them were rational, concious beings, but less so than humans. (Muhammad ibn Ali al-Baqir pbuh said: Since the creation of the earth, God Almighty has created seven peoples who are not descendants of Adam. He created them from the soil of the earth and caused them to inhabit it, one after the other, each with his own people. Then, God Almighty created the father of this mankind, and He created his offspring from him." Al Sadooq 1982, 359. Arabic source, translated. Also Al-Ayashi 1991, vol. 2, 238.) This religious account and others indicate that concious, intelligent life forms have evolved on this earth. In this account, there are seven generations that are concious and intelligent, whose souls are different than Adam, who are not from his children, and who preceded him pbuh on this earth. (The Prince of the Believers, Ali pbuh said: "God Almighty wanted to create a creation with His own hands after 7,000 years of Jinn and Nisnas existing on earth. He wanted to create Adam... I want to create a creature with My hands, and I want to make from his offspring prophets, messengers, righteous servants, and guided Imams, and make them vicegerents among My creation on My earth, who command them against disobeying Me, warn them of My torment, guide them to My obedience, and guide them to the path toward Me. I shall make them Proofs of Mine upon the others, and I will exterminate the Nisnas on My earth and cleanse it of them." Al-Qumi 1983, vol 1, 36. Arabic source, translated.) This religious account clearly says that before Adam pbuh there were human-like beings on the earth. It is clear that the seven thousand years are not units of measurement familiar to us today. We can imagine different time units of measurement that are not familiar to us, because they are in different dimensions outside of the universe which we live."
The two Shia hadeeth (narrations) are over 1000 years old, as Imam Ali ibn Abi Talib pbuh lived from 601-661 and Imam Muhammad ibn Ali al-Baqir lived from 677-733.
