There is absolutely nothing that speaks of them, and in the absence of positive fact we can only fall back upon mere hypothesis, more or less probable, until an accurate investigation with regard to the origin of this primitive people may present us with a convincing theory.
But in order to make these studies it would be necessary to live in their midst (and not many could adapt themselves to the various inconveniences of such a life) because the live Sakai never abandons his native forest and to have a dead one for the purpose would be next to impossible, as he who attempted to carry away a corpse would expose himself to serious danger, there being no greater sacrilege, according to the idea of these bushmen, than that of touching a dead body or of digging up the ground where a skeleton lies.
Therefore there does not seem to be any near chance of arriving at a definite conclusion upon the subject.
It is generally believed that anciently a people, called Benuas, not willing to submit themselves to the laws imposed upon them by the then flourishing and civilized India and fearing to fall into slavery, advanced through Indo-China till they reached the Malay Peninsula. Here also they found themselves pursued and surrounded by civilization, so, instead of settling round the rich and smiling shores, they turned towards the forest and encamped there. This version of their immigration would account for the Sakais not having the least idea of the sea which they never mention, not even in their legends or superstitions.
Shunning-all contact with the other inhabitants of the country they had chosen as a refuge, they concealed themselves in the jungle, thus preserving their independence and the purity of their race.
Some centuries later, in an era of fanaticism, invasions were made upon them with the object of converting them to Mohammedism but the only result was fire and bloodshed and after each conflict the surviving Sakais fled further into the forest (into those parts which had never been before explored) or to the natural strongholds of the far off mountains.
If this hypothesis holds good then the Sakais must be a very ancient people. It is an accepted fact that as far back as the 8th century Arabian merchants traded with the inhabitants of the Peninsula and that a very remote intercourse existed between these and Hindostan, and although there is no substantial proof, no analogies of language, customs or creed upon which to base such a conjecture, neither, as yet, has anything been proved to the contrary whilst many primeval superstitions prevalent amongst the Sakais are still to be found in other tribes living in proximity with believers in Buddha and Brahma.
Another legend, sustained by the Kurumbus themselves, would make one suppose that the Sakais belong to that people, once grand, but now broken up and dispersed. In fact, even at the present time, there are many popular songs amongst the Malays in which the Kurumbus and Sakais are mixed up together.
Dr. Short, in his ethnological studies of India, describes certain characteristics and habits of the Kurumbus, inhabiting the forest, which perfectly coincide with those to be met with amongst the Sakais.
