On the Infinity and finity of human imagination

I had heard and read quite a lot of things which discussed the infiniteness of human imagination. Indeed human imagination can conjure the most bizzare things ; my imagination as a child was the none the less I remmeber developing an idea of a future Autotrophic human with green hair {with the chlorophyll} ......an eight year old's solution to food crisis of the world ! as a child I was compelled to believe after reading abt fairies , alice in wonderland and other inventions of human imagination coupled with the satisfaction that I cud imagine whatever I like and want ........Human imagination was the only thing that could compete with universe for the title of being infinite . It seems so very obvious to even an adult that imagination is limitless ........
space travel , electricity , computers all are a product of that fantastic thing called imagination
thats what has brought us ... from a eat sleep drink reproduce caveman to what we are today !
But yes , is this infinte ? I must agree that for every practical purpose this is the infinity .
Leaving the practicality back lets take a little theoratical approach . thats what I did to kinda
a come to the conclusion currently that human imagination is not quite infinte. that brings us to the question whats n how much is infinite. An age old maths tells me If I have 2 sets
Set A = { 1, 2 , 3, 4 .......} Set B = { 1 , 4 , 9, 16 ..........} . both the sets are infinte even though set B doesnt have all the elements in Set A . I believe human imagination is infinite .....buts its infiniteness is like Set B not like Set A.The reason why I say this is quite simple .Human imagination has one huge weak point like all other systems of human origination have.That weakness comes from the fact that human perception is very limited . Humans cant percieve anything beyond the 5 sense organs . precisely We cant percieve anything that we cant touch , smell, see, hear and taste. and even if we do percieve something which we often refer to as 6th sense ......it needs a interpretation which is again bounded 5 sense of organs. I guess its the technical implication of situation....where We cant express ourselves in words . In this case its the weakness of the language that theres no word invented to express the current feelings similarly in my argument .....theres no perception and sensation of certain phenomenas which do happen in universe .
Science says still theres no proof of life in outer space ......I say we can have life verymuch
on this planet earth itself which we dont know off particularly because we arent able to percieve their existance. its like a situation where a Very intelligent man who has just reached a certain very importrant breakthrough in a problem facing human beings for decades , wants to tell others abt it but he is deaf and dumb , doesnt have hands and legs.
how the hell can we percieve if he wanted to tell . the whole problem with imagination is thats its based entirely on human perception which is why its so very limited , yet following properties of Set B it is infinite in the domain of perception !
Offcourse we cant ignore the fact that the concept of infinity has come from this infite imagination of ours. So is it case of concept outgrowing the creator , I guess yes .but still salute to our imagination cause it could develop a concept whose implication are indeed infinite, infinite like Set A. Indeed there are more concepts which are product of our imagination like a point which is dimension less ......so what is it ? we dont know . Also concept of zero. huge implication
But ,
I would like to conclude here due to lack of time saying I have imagined all this !
