Sir Lal, scripture existed long before the time of Lord Buddha. It is incorrect to say that Lord Buddha was not aware. The Rig Vedas, which are the sacred texts of Hinduism, were written more than a millennium before the birth of Bodhisatta. Brahmāyu read these texts. He did not know the real meaning of these texts because he had no ariyas to teach him. Let us not forget that he was 120 years old when he met Lord Buddha. For 120 years, despite his knowledge, he was not even close to being a sotāpanna. I think that in his infinite knowledge, Lord Buddha knows the scripture. Lord Buddha did not say to write down the texts simply because it was useless without Ariyas to teach. Lord Buddha’s age is the golden age of ariyas no need to write. We need to listen with our ears to grasp the Dhamma. If no ariya is there to teach the texts are completely useless. Let us not forget that the ability to realize Nibbāna will disappear with the death of the last Jati Sotāpanna. The texts and websites will be there but, no one will reach Nibbāna because there is no ariya to teach. I am sure that by that time, humanity will be very technologically advanced, but even if we take videos of the ariyas, it will be impossible to reach Nibbāna. We need a living ariya to teach us.
This is the point that Christian and I are defending. Of course, everyone is free to doubt this, but it is supported by proof of the suttas.

This is also why Lord Buddha says that spiritual life is 100% dependent on noble association. See the Kalyāṇamittasutta
“Great king, this one time I was staying in the land of the Sakyans where they have a town named Townsville.
Ekamidāhaṁ, mahārāja, samayaṁ sakkesu viharāmi nagarakaṁ nāma sakyānaṁ nigamo.
Then the mendicant Ānanda came to me, bowed, sat down to one side, and said:
Atha kho, mahārāja, ānando bhikkhu yenāhaṁ tenupasaṅkami; upasaṅkamitvā maṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinno kho, mahārāja, ānando bhikkhu maṁ etadavoca:
‘Sir, good friends, companions, and associates are half the spiritual life.’
‘upaḍḍhamidaṁ, bhante, brahmacariyassa—yadidaṁ kalyāṇamittatā kalyāṇasahāyatā kalyāṇasampavaṅkatā’ti.
When he had spoken, I said to him:
Evaṁ vuttāhaṁ, mahārāja, ānandaṁ bhikkhuṁ etadavocaṁ:
‘Not so, Ānanda! Not so, Ānanda!
‘mā hevaṁ, ānanda, mā hevaṁ, ānanda.
Good friends, companions, and associates are the whole of the spiritual life.
Sakalameva hidaṁ, ānanda, brahmacariyaṁ—yadidaṁ kalyāṇamittatā kalyāṇasahāyatā kalyāṇasampavaṅkatā.
A mendicant with good friends, companions, and associates can expect to develop and cultivate the noble eightfold path.
Kalyāṇamittassetaṁ, ānanda, bhikkhuno pāṭikaṅkhaṁ kalyāṇasahāyassa kalyāṇasampavaṅkassa ariyaṁ aṭṭhaṅgikaṁ maggaṁ bhāvessati ariyaṁ aṭṭhaṅgikaṁ maggaṁ bahulīkarissati.
