[Quranic Reflection]: Quran vs Hadith- why the Hadith is false

[R00tKiT]

( 78 )   And indeed, there is among them a party who alter the Scripture with their tongues so you may think it is from the Scripture, but it is not from the Scripture. And they say, "This is from Allah," but it is not from Allah. And they speak untruth about Allah while they know.

You always hear "Muslims" who come to you and "twist their tongues" to spit "Hadith narrations" in an attempt to make what they say holy like the scripture. 

 
The verse refers to anyone who tries to mimic scripture to confuse people. This doesn't allude at all to hadiths, because they are not an attempt to imitate scripture.

2-Prophet Mohammed -peace be upon him- had nothing but the Quran as a source book; the revelation that came to him from God is "the Quran" only:

Sura 6, The Quran:

( 19 )   Say, "What thing is greatest in testimony?" Say, "Allah is witness between me and you. And this Qur'an was revealed to me that I may warn you thereby and whomever it reaches. Do you [truly] testify that with Allah there are other deities?" Say, "I will not testify [with you]." Say, "Indeed, He is but one God, and indeed, I am free of what you associate [with Him]."

( 20 )   Those to whom We have given the Scripture recognize it as they recognize their [own] sons. Those who will lose themselves [in the Hereafter] do not believe.

( 21 )   And who is more unjust than one who invents about Allah a lie or denies His verses? Indeed, the wrongdoers will not succeed.

Where do these verses say that the prophet had ONLY the Qur'an ? Where is the word only in the verses...? 

3-A direct and clear threat was given from God to any person who comprise false scripture and say "this is from God !":

Hadiths aren't a substitute to the Qur'an, they are a necessary complement. What's so hard to understand about that ?
Also,  sunnism doesn't claim hadiths come from God verbatim.

4-There are so many Muslims -and you saw many of them in this forum and outside- who reject the Quran and say it is either not enough or not obvious enough when a religious matter is under discussion-, instead they paste to you walls of text from Hadith books:

We don't reject the Qur'an, you're trying to build a strawman to make it easy for yourself.

5-Concealing the Quran is a cursed deed, the Hadith is an attempt to conceal the Quran and replace it:

That's hilarious. Many hadiths actually encourage reading the Qur'an and promise heavenly gratification for reciting some of its chapters.
