- Many sites claim that there were Two buddhas and both were different.
- It is said that Adi buddha was the real avatar of lord vishnu.
- Gautama buddha was only a enlightened one but not an avatar of lord vishnu.
- Is this concept of two buddhas are real ?
- Which buddha is the real incarnation of lord vishnu ?
For the most part, I think it is Gautama Buddha who is the incarnation. This is because of the fact that Swami Vivekananda mentioning it in his famed lectures at the parliament of religions at chicago. Again, Jayadeva mentions it in his Gita-Govinda. You can also see the Wikipedia post for pictures of Lord Buddha as an avatar.
I think Buddha is mentioned in many Puranas like Agni,Padma,Vayu,Vishnu and few others.In all of them simply Buddha is mentioned or the term "Bauddha" is used.Although not sure if by "Bauddha" is meant the followers of Tathagata Buddha or simply those sects who don't follow Sruti and Smriti texts.
The Agni Purana ,however,mentions Buddha as one of the ten avatars of Lord Vishnu.
As there was an ongoing battle of Devas and Asuras for long time, Devas approached Lord Vishnu to revive ‘Dharma’ and ‘Nyaya’ and beseeched Him to take human form once again. The Lord said that ‘Mayamoha’ would soon take birth as Buddha to one Sudhodana. But the illusions that would be created in the name of Buddha would be such that many evil persons would call themselves as Buddhists and undo all the Golden Traditions established in Vedas and other Scriptures. The misleading ways would advocate materialism in detestable manner and finally end up in the last phase of ‘Kali Yuga’
In Bhavishya Purana,Goutama Buddha is mentioned but not as an incarnation:
In the initial years of Kali Yuga, the survivor Mlecchas gradually adopted responses to the new environs, new ways of life and even new language styles.For instance, earlier languages got corrupted and new expressions emerged; Vraja Bhasha, Prakruti, Sanskrit etc. got adapted from Gurundika (English) which was also different from Mleccha Bhasha/ Yavani and new corruptions of various languages both in spoken and written scripts got adapted..........
Magadha Kingdom was segregated from Arya desha and was surrounded by Kalinga (Orissa) in Agneya or South East, Avanti in South, Aanart (Gujarat) in Nirruti or South West, Sindhu to the West, Kaikadesha in Vayavya or North West, Madra Desha in North and Kulinda in Ishaanya or North East. In the lineage of King Magadha was the famed Ajata Shatru.
The contemporary times of the Magadha Kings witnessed the emergence of Buddha Dharma set up by Goutama Buddha at Kapilavastu.The emphasis of Buddhism was on Truth, Virtue and Non-Violence which are already part of the traditional Vedic Dharma but were against the consequential Rituals. Goutama's philosophy created high waves and eventually secured wide spread acceptance especiallly supported by Kings and large sections of common persons. It was in this lineage of Kings were Sakya Muni-Shuddhodana-Sakyha Singha-Buddhi Simha-Chandra Gupta.
In any case, there some people who consider that Bhavisya Purana has been interpolated.
Adi Buddha is an avatar of Vishnu lived from 1887 BC to 1807 BC born to Mother Anjana and Suddhodana in (Bodh Gaya). He born in the Same Ikshvaku dynasty in which Rama also born. The Adi Buddha Established the Philosophy of Ahimsa, Non Violence. He preached against ritual Animal Sacrifices that has crept into Vedic Hinduism.
Siddhartha was born in 6th century BC in Royal Family of Suddhodana and Mayadevi in Lumbini in Nepal. Siddhartha received his name Gautama from his Guru Gautama Muni, who belongs to Kapila dynasty. He renounced his palace comforts to find enlightenment. He went to Bodh Gaya to meditate and got enlightenment. He meditated at the birth place of Adi Buddha.
If you look at the various arguments, you can say there were two Buddhas. Adi Buddha is the founder of Buddhism with Hindu philosophy. Gautama Buddha is not an avatar of Vishnu and who rejected Vedas and established modern(Neo) Buddhism.That's why you can still find remnants of Hindu thoughts in Buddhism.
Because Adi Shankara, who revived Hinduism after destroying the spread of Buddhism, gloried the path of Buddha.
I worship the spiritual radiance manifested as Buddha, who was all-knowing, who was the conqueror of Mara, who was full of mercy, who was of the nature of Buddhaand who was the adored of those who were opponents of Yajnas.

The 21st incarnation of Vishnu is Janardan/Adi Buddha. He was the son of Jin. Jin was a famous king of Magadh. At the time of the starting period of Kali yuga Narayana decided to come to the earth for protecting the people who was suffering from fainted and foolish knowledge..

By logic they both can be "The" Buddha, since Lord Vishnu's eternal promise to humanity is that he will manifest himself whenever humanity are in great need.
stated in the Bhagavad gita, whenever evil gains ascendance, God incarnates on earth to restore dharma, punish the evil and protect the weak and the righteous
