It doesn't mention the end times, here's what the hadith says:
It was narrated that Thawbaan, the freed slave of the Messenger of Allah (blessings and peace of Allah be upon him), said: The Messenger of Allah (blessings and peace of Allah be upon him) said: “There are two groups of my ummah whom Allah will protect from the Fire: a group who will conquer India, and a group who will be with ‘Eesaa ibn Maryam (peace be upon him).”
Narrated by an-Nasaa’i (no. 3175) and Imam Ahmad in al-Musnad (37/81). Classed as saheeh (i.e authentic) by al-Albaani in as-Silsilah as-Saheehah (no. 1934).
Some say it has already occurred, others say that because the hadith also mentions Isa (Peace Be Upon Him) that the conquest is to occur in the end times.
Ibn Katheer
said in his book "An-Nihaayah Fil-Fitan Wal Malaahim": “Indeed, the Muslims conquered India in 44 (A.H) during the reign of Mu’aawiyah Ibn Abi Sufyaan and some incidents took place and we mentioned them in detail. Also, the great king As-Sa’eed Al-Mahmoud Ibn Subiktikeen, the ruler of Ghaznah and its surroundings conquered it in about 400 (A.H) and he did there some renowned acts and good matters and he broke the great idol called "Somnath" and took its garlands and swords and returned to his country victorious and safe."
Shaykh Hammoud At-Tiweejri said: “What was mentioned in the Hadeeth that was reported by Nu’aym Ibn Hammaad from Abu Hurayrah about the conquest of India, has not yet taken place, and this will happen when ‘Eesa will descend"

All other hadees on the subject are not sahih/hasan, so we cannot accept them. The hadith also mentions nothing about conversions, it just mentions conquest. Converting you guys isn't required.
The hadith is pretty clear and not vague at all.
Because as I said, the statements are not meant to be used for scientific knowledge, they are meant to tell us about the signs that the end of days is near. Learn to read people's posts properly.
Dinosaurs are not relevant to the religion, so why would they be mentioned? If you guys are stupid enough to deny everything else, you'd probably also deny dinosaurs being mentioned even if they clearly were.
