On raining and science

I was very young and it was a very hot summer in the place I lived. I wanted it to rain badly. Rain anywhere is a delight, but in those lush green, wide lawns and courtyards that circled our single storey houses , a downpour came to become one of the most amazing experiences of childhood. We had swings in our courtyard and you can only experience the thrill of riding one in rain if you have done it. We made paper boats before we knew it was called origami and it was a beautiful sight when rain restored color to all the surroundings. So I wanted rain really bad. One of my friends told me to kill an emmet, hang it by the thread on the clothesline, It would make rain. This trick was confirmed by two other girls who swore by it . So I did just that. But it didn't rain. It gave me something to think about.
The very next week we read about the water cycle in our science class. And I had an enlightening moment. I knew something about this made sense that hanging an emmet by a thread didn't do. It actually described the whole process. I went home, took the biggest tub I could find , filled it with water upto the brim , put it in the middle of our garden and waited for it to evaporate and make rain. As luck would have it , it rained.
-Ammi had made pakoras.  I thought I could say it always rains when she made pakoras but somehow i couldn't.
- She also complained that it rains always when she hangs the clothes to dry. I knew something was off about this observation. Rain couldn't possibly bother about all that.
In my own little, childish way I had learnt some things namely ;
- "CORELATION ISNT CAUSATION"
A concept that many  adults in my life still mix up all the time
-  CAUSE PRECEDES EFFECT. Rain led to Ammi making pakoras. Not vice versa.
-  CONFIRMATION BIAS. (This took me a while to understand). When you are really sure of your beliefs, you seek only to confirm them and in doing that you may overlook facts.( A tub full of water wouldn't have caused rain , it was too small a surface area. In my own mind though , I had proved the water cycle )
On the other hand , if conditions of your experiment aren't accurate, you cannot possibly testify a hypothesis. Had it not rained, it wouldn't have meant that water cycle is wrong. It would simply have meant I didn't use a tub that was large enough.
