فَأَزَلَّهُمَا ٱلشَّيۡطَـٰنُ عَنۡہَا فَأَخۡرَجَهُمَا مِمَّا كَانَا فِيهِۖ وَقُلۡنَا ٱهۡبِطُواْ بَعۡضُكُمۡ لِبَعۡضٍ عَدُوٌّ۬ۖ وَلَكُمۡ فِى ٱلۡأَرۡضِ مُسۡتَقَرٌّ۬ وَمَتَـٰعٌ إِلَىٰ حِينٍ۬ (٣٦) فَتَلَقَّىٰٓ ءَادَمُ مِن رَّبِّهِۦ كَلِمَـٰتٍ۬ فَتَابَ عَلَيۡهِۚ إِنَّهُ ۥ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ (٣٧) قُلۡنَا ٱهۡبِطُواْ مِنۡہَا جَمِيعً۬اۖ فَإِمَّا يَأۡتِيَنَّكُم مِّنِّى هُدً۬ى فَمَن تَبِعَ هُدَاىَ فَلَا خَوۡفٌ عَلَيۡہِمۡ وَلَا هُمۡ يَحۡزَنُونَ
2:36 But Satan caused them both (men as well as women) to stumble therein and got them out of the happy state they were in. And so We said, “Degraded you have become with wedges of discord among yourselves! There shall be for you habitation and livelihood on earth for a while.”
2:37 (The solution to this catastrophe was beyond human redress.) Then Adam received Words of guidance from his Lord and He accepted his repentance. Certainly, He is the Acceptor of repentance, the Most Merciful.
2:38 We said, “For now, all of you are degraded to a lower level of existence, out of this state of felicity (Paradise). But, when guidance comes to you from Me, those who will follow My guidance, on them shall be no fear from without, nor shall they have any grief from within.”
Please reflect on above verses. Humans are told in 2:36 that their habitation and livelihood is on the earth for a while. 2:38 tells us that if we follow the guidance whenever we receive it from God then there is nothing to fear or grieve.
Now can we live on other planets. Please see following verses:
يَـٰمَعۡشَرَ ٱلۡجِنِّ وَٱلۡإِنسِ إِنِ ٱسۡتَطَعۡتُمۡ أَن تَنفُذُواْ مِنۡ أَقۡطَارِ ٱلسَّمَـٰوَٲتِ وَٱلۡأَرۡضِ فَٱنفُذُواْۚ لَا تَنفُذُونَ إِلَّا بِسُلۡطَـٰنٍ۬ (٣٣) فَبِأَىِّ ءَالَآءِ رَبِّكُمَا تُكَذِّبَانِ (٣٤) يُرۡسَلُ عَلَيۡكُمَا شُوَاظٌ۬ مِّن نَّارٍ۬ وَنُحَاسٌ۬ فَلَا تَنتَصِرَانِ (٣٥) فَبِأَىِّ ءَالَآءِ رَبِّكُمَا تُكَذِّبَانِ
55:33 O Communities of the nomads and the urban! If you can break through the fences of the heavens and earth, then, break through. Never can you break through without an authority (which you won’t have). Can you bring any evidence?
55:34 Then, O Men and women! Which authority of your Lord will you deny?
55:35 A blaze will be unleashed upon you, and thick smoke, and you will not be able to defend yourselves.
You can decide yourself if we can leave the earth to live somewhere else without the sustenance we get from the earth.
