'Entstehen' (to arise) is an inseparable verb made up of 'ent-' and 'stehen' (to stand). It describes how something new comes into being, often as the result of a process.
Aus einer kleinen Idee ist ein großes Projekt entstanden.

The perfect tense of 'entstehen' (to arise) is always formed with the auxiliary verb 'sein' (to be), because it describes a change of state (from nonexistence to existence).
Wann ist dieses Gebäude entstanden?
When did this building arise?
To name the cause or origin of something, 'entstehen' (to arise) is often combined with the prepositions 'durch' (through/by, naming the cause) or 'aus' (from, naming the material/source).

'werden' and 'entstehen' can both describe that something new happens or develops. 'werden' is used when someone or something gets a new state or a new quality: 'Es wird dunkel' (It is getting dark), 'jemand wird krank' (someone becomes ill), 'ein Plan wird wichtig' (a plan becomes important). 'entstehen' is used when something begins to exist or forms, often as the result of something else. A problem, damage, or an idea can 'entstehen'. Learners may confuse the words because both express development. In practical terms: 'werden' fits a new state, while 'entstehen' fits something that newly exists.
