Why are the five pillers of islam so important to muslims

The five pillars of Islam are
Salah; basically the prayers that Muslims carry out five times a day,across five different parts of the day; they are fajr (early morning), duhur( afternoon), asr(mid afternoon), Maghreb (sunset) and isha (night)
Zakah; when Muslims put a part of their wealth aside to give it to the poor people
Sawm; when Muslims fast in the holy month of Ramadan for 30 days. They don't drink water or eat any food. They wake up at fajr, eat a little bit then break their fast at Maghreb
Hajj; when Muslims travel to he holy site of a Mecca and perform their pilgrimage/ taw after around the kaabah
Shahadah; when Muslims bear witness that there is no god by Allah (the most glorified, the most high) and Muhammad (may the peace and blessings of Allah be upon him) is his last messenger
