The word 'his god' mentioned in the question is wrong as it was not his god but Allaah.
I would want to ask the questioner that how do you know that you are a human? Your would be obvious, highlighting the arguments regarding the features of a human which he has.
The same is true for this question, Rasoolullaah (saws) knew that to whom he conversed was not from the creations of this world. He was the One Who is not seen by anyone. The things told to Rasoolullaah (saws) were such, which cannot be said by anyone but Allaah. Can anyone of this world bring a verse like that of Qur'an? This challenge is mentioned in the Qur'an.
H. Muhammad pbuh is last prophet of the God .
By and large, this is an acceptable definition of Muslims. Some might make nuanced critiques of the wording, but generally speaking, Muslims are those who submit to God's will and follow the laws and dictates that Muhammad revealed for that God.
According to Islam, Muhammad is not a God, but a man.

Muhammad was the last prophet from God.
Muhammad is Allah (God in English) prophet who received God revelation of Quran; that reflects real God words in its real Arabic language; through the angel Gabriel (Jibril). Prophet Muhammad calls people to worship of God; the one and only one God with no partner, no son, no companion, and no associate. Refer to question and link below.
We do not worship Muhammad. God forbid ! We only worship the One God. Muhammad was God's Messenger and Prophet, and His beloved servant. That is all.
I believe that the Mormons (at least the Church of Jesus Christ of Latter-day Saints) are speaking the truth of God. Of course, that may just be because I am an LDS, but I still strongly know and believe that we are speaking the truth about God.
God (Allah in Arabic) is the Creator. Prophet Muhammad is God prophet per God revelation of Quran to him through the angel Gabriel (Jibril). However, it is to be emphasised that prophet Muhammad is a human who is inspired by God.
Islam has one god that has 100 names and that Muhammad is his last messenger. ps. the Muhammad I am talking about is (Not) Muhammad Ali
Muhammad (PBUH peace be upon him) is the 3rd prophet of the Abrahamic faiths including Christianity and Judaism. The Quran, Islamic holy book, was revealed to prophet Muhammad (PBUH) through the archangel Gabrael. Muslims view Muhammad (PBUH) simply as a prophet. They neither worship nor pray to him. They pray to God and God only. They do not believe God has any partners. They believe all humanity are God's children. God is referred to as Allah in Arab speaking countries because Allah is simply the Arabic word for "God." Even Christians and Jews living in Arab and Muslim countries call God Allah. Allah is not a separate or different God than that of Christians or Jews.
Islam religion per God Quran revelation to prophet Muhammad is founded by Allah (God in English and same God in Christianity and Judaism) and not prophet Muhammad (peace be upon him). Prophet Muhammad is the God Messenger and prophet who conveyed God message to his followers. Refer to related question below
