Another proof that Jesus has died is the Verse of the Holy Qur'an:
وَالَّذِينَ يَدْعُونَ مِن دُونِ اللَّـهِ لَا يَخْلُقُونَ شَيْئًا وَهُمْ يُخْلَقُونَ ﴿٢٠﴾ أَمْوَاتٌ غَيْرُ أَحْيَاءٍ ۖ وَمَا يَشْعُرُونَ أَيَّانَ يُبْعَثُونَ
Those whom they invoke besides Allah have not created anything, but are themselves created. (20) (They are) dead, lifeless, and they know not when they will be raised up. (Sura 16:20-21)
Incidentally, after Allah, Jesus is the person who is most invoked as an object of worship, since Christianity is the most widespread religion in the Earth. And Jesus is included in the category of "Min Dooni Allah" (Sura 5:116). So Allah says those that are invoked besides Him are Amwaat "Dead" Ghayru Ahyaa'in "Lifeless"
This verse is regarding Idols not Isa(as) for the following reasons:
1. Even Angels and Jinn were worshiped, so as per your logic, they should be dead.
And [mention] the Day when He will gather them all and then say to the angels, "Did these [people] used to worship you?" They will say, "Exalted are You! You, [O Allah ], are our benefactor not them. Rather, they used to worship the jinn; most of them were believers in them.(34:40-41)
But they have attributed to Allah partners - the jinn, while He has created them - and have fabricated for Him sons and daughters. Exalted is He and high above what they describe.(6:100)
2. The next verse after the verse you quoted says that its about people who didn't believe in hereafter.
Your god is one God.
But those who do not believe in the Hereafter - their hearts are disapproving, and they are arrogant.(16:22).
These weren't Christians as they believe in hereafter. These were polytheists of Makkah, who believed in idols such as Lat, Manaat, Uzza, etc.
Quran clarifies this issue in another chapter, that the idol worshipers of Makkah are the ones who don't believe in hereafter:
So have you
considered al-Lat and al-'Uzza? And Manat, the third - the other one? Is the male for you and for Him the female? That, then, is an unjust division. They are not but [mere] names you have named them - you and your forefathers - for which Allah has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance. Or is there for man whatever he wishes? Rather, to Allah belongs the Hereafter and the first [life]. And how many angels there are in the heavens whose intercession will not avail at all except [only] after Allah has permitted [it] to whom He wills and approves. Indeed,
those who do not believe in the Hereafter name the angels female names,(53:19-27).
