Hey guys like the title says, I always try to debate with my teacher after class on things in philosophy but when we inevitably get into religion, because I cite that as my reasons for not doing things like killing and giving stuff to the poor, he starts off by saying that the Quran has errors
If you think you won't have the answers, i think its better you study the religion abit more in depth first insha Allah.

May Allah help you and us all, ameen.
like the setting the sun in a certain place,
Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people...
[Qur'an - Surah Al Kahf 18 : 86]

This is what alot of anti Islamic people use to attack Islam, claiming that the sun sets when science proves otherwise. There is no error in the Qur'an, its simply a figure of speech. The same way we know today that the sun does not set, yet people still use the word 'sunset' and 'sunrise.' There is no error, but those who hate Islam will do anything to try to discredit it, even though their own cultural or linguistic figure of speech is similar.
claiming taht Allah says taht all christians are my enemy,
Nope, not all non muslims are enemies;
At the time of the Messenger of Allah, there were some christians who gave refuge to Muslims in Abysinnia [ethiopia] so the following verse was revealed;
..you will find the nearest of them in affection to the believers those who say, "We are Christians." That is because among them are priests and monks and because they are not arrogant.
[Qur'an 5:82]
Anyway, this verse is important also;
Allah forbids you not, with regard to those who fight you not for (your) Faith nor drive you out of your homes, from dealing kindly and justly with them: for Allah loveth those who are just.
[Qur'an 60:8]
saying that the Quran claims that the earth was created before the stars and that the universe was made in six stages and that it was smoke in the begiinning then saying taht these are inaccuracies.
These links are all relevant insha Allah;

today told me that in one part of the Quran God says that he would smite anyone who says he doesnt exist and started saying to the sky "God does not exist" then saying that nothing happened.
Allah doesn't simply destroy a people because they deny His existence, rather He gives them trials in this life so they may return to Him, since humans are by nature dependant upon a greater power.
And verily, We will make them taste of the near torment (i.e. the torment in the life of this world, i.e. disasters, calamities, etc.) prior to the supreme torment (in the Hereafter), in order that they may (repent and) return (i.e. accept Islam).
[Qur'an 32: 21]
However, if they die being ungrateful to Allah as disbelievers - they will face the severe punishment since this life is a mixture of both good and evil, whereas the hereafter is of either pure good reward or total punishment. We pray to Allah to make us of the successful and not of the losers.

Thanks brothers and sisters!
I know i havn't been able to address all the questions, but i think it's important you only debate once you're more knowledgable of Islam in depth.
