ELI5: Why does inflation even occur? Can't we just "reset"/"deflate" the value of money?

Edit: Sorry I realised I should have phrased my question better. 

Correct ELI5: Why can't we just reset/deflate the value of money when inflation occurs to prevent prices from becoming exorbitantly high over a long period of time resulting in everyone having to pay for simple items using colossal amounts of cash?  

^Which I now understand is unfeasible and impractical, at least for now. Thanks for all your answers! :)

A small amount of inflation is pretty hard to avoid in a growing economy - you need more money circulating so that everyone has money to spend, rising wages means sellers can charge more for their goods, etc. And it's not a bad thing - it encourages people with lots of money to spend or invest it, as it is slowly losing value sitting in a bank, which frees up capital for further growing the economy.

You can deflate or reset a currency but both have problems. 

Deflation has the opposite effects - people hoard money (it'll be worth more if you spend it tomorrow), which means less new business and existing businesses selling less, which leads to cutting employees, etc. which can spiral down into nastiness quickly.

Resetting currency is really worse. It's hugely complicated and expensive, and it has a tendency to make other people very skeptical of your currency. Lots of unstable countries with high inflation have done things like say, "Ok, as of today every 100 old dollars now equal one #Strong Dollar" - that doesn't actually change anything, except make businesses move the decimal point on price tags, but it does tell the world "Our currency is really fucked and we can't fix it", so no one wants to do business with your currency that might suddenly get devalued again.
