Like how does fruit know to be sweet to persuade us to eat it and shit the seeds somewhere else? How do chilies know that only birds are immune to spice of capsaicin so that they will eat it and take the seeds further when they fly somewhere else? Did they plan this or was it an accident?

It was accidental evolution. Millions of different fruits evolved with different tastes, but some happened to be sweet.
The sweet ones were able to outcompete the non-sweet fruits because more animals ate the sweet ones, spreading their seeds.
This gave them a huge advantage in reproduction and eventually they became the more dominant fruit tree, and the fact that animals enjoyed them meant they would not die out.
