Yes, Philippine literature existed way before the Spaniards came. While not many of this literature has been committed into writing until recently, epics, tales, and various prose and poetry have existed pre-Spanish colonization. Much of the literature that has been handed down to us are from indigenous tribes and the Moros. The Maranao tribe of the South has Darangen. Biag ni Lam-ang has been put into writing in the Spanish era but is an existing lore of the Ilocanos. There are also countless myths and stories that have been passed down from generation to generation. Finally, one proof that Philippine literature existed pre-Spanish colonization is the Baybayin. The Baybayin is an old form of writing that was used by the Tagalogs. It tells us that our ancestors had the need to transcribe some things and scholars believed it included their myths and epics. Sadly, when the friars came, they made it their mission to wipe out whatever literature they could find as they viewed it as sacrilegious.
Philippine Literature was exist early times before the Spaniards came. It is TRUE that Filipinos have already literature in later times. It is because our ancestors have already an Alphabet that times and they were called it Malay-Polynesian or the Alibata.
