Then the Bible Old and New Testament are considered to be lies or is it something else?

The Bible, Old Testament and New Testament are considered corrupted in Islam.

We believe that there was an original message. Good people practiced it. That Satan has tempted people to change it over time. Then Muhammad (peace be upon him) brought the Qur'an which claims to be the original message, and it claims to stay free from corruption.

I won't debate you if that's true or not, nor I'll debate you whether the Qur'an is "preserved" as we claim or not. Just what we believe.

I have heard that before but the New Testament is older than the Quran and currently there are over 5,000 known manuscripts (pre-printing copies of a text) of the New Testament in the original Greek language.

Yeah, New Testament should be around 600 years older than the Qur'an. The Old Testament should be much older. But it's historically proven to be changing with time. (Just look at comparison between New Testament scripts from different centuries.)

Jesus spoke Aramiac, and the oldest Bible manuscript we have is in Greek, I believe, (I may be wrong,) so that alone may raise questions about how accurate it is, compared to what Jesus told his people.

Qur'an was revealed with stories that we as Muslims believe to be the "correct" unchanged versions, that should've been in the first Bible. But who knows? I believe Islam is true, because of my life experiences, so I believe the Islamic version of stories to be more accurate.

Yes but there was many copies of the Quran that were burnt to end controversies. Islam is a religion of force. Hence, Constantinople is called Istanbul. Christianity spreads through miracles and martyrs. Love not force. God is love.

Islam acknowledges that force can (also) be used for good.

As for the burnt Quran copies, Qur'an has different readings, and the Arabic writing was not standardized at first. The books that were burned are Mushafs (Qur'an books) that were written in a different way than the standard.

Still, the main way Qur'an was preserved is via Oral Tradition, and there are multiple ways it could be read, but (as far as I know,) they're not contradictory, and complement each other, both in sound and meaning.

Here's one video I liked about different "Readings" of the Qur'an:

Speaking of different ways to read Qur'an, my aunt has learned at least two of them, and if she lived long enough, she strives to memorize all of them from memory.
