There are two things I can agree with you.

• the universe cannot come in existence by chance
• if God created the universe he must be perfect

However Allah is not perfect and he admits that himself.

• the quran contains commands that abrogate each other if they contradict
• The best argument for the quran is that "you cannot even make a chapter similar to the quran" so it must be from Allah

Muhammad always got revelations from Allah when it was the most convenient for him and he always excused his sins as if it was from God instead of repenting from his sins.

Also, you seem to misunderstand the trinity (Father, Son, Holy spirit) if you say Jesus would be Gods successor according to Christians. The way the trinity works is similar to molecule. O_3 is an oxygen molecule with 3 oxygen atoms, it's still 1 oxygen.
The Bible is the story of:

• God creating a perfect world
• Sin entering the world and tainting it
• God saving his creation by entering in it as a human (Jesus), living a sinless life, dying for the world as the perfect sacrificial lamb and ressurecting so we can have life in him.

Even the quran agrees on the fact that Jesus of all people will come back for judging the earth.

Just a few thought, feel free to disagree but don't mistake the truth for lies.
