Buddhism
In Pali texts, the first Buddha in Buddhavamsa sutta was Taṇhaṅkara Buddha. The Mahapadana sutta says the earliest Buddha of the recent seven buddhas was Vipassi Buddha (But sutta is not saying that Vipassi is first Buddha). Counting from the present kalpa (the beginning of our present world (Earth)) Gautama Buddha is considered the fourth Buddha. In this telling, the first is Kakusandho Buddha, second Konakamano Buddha, and the third Kassapo Buddha. The last Buddha of this kalpa will be Maitreya Buddha. Then the world (Earth) will renew itself and from then begins a new kalpa.
