Some people have large brains while others have a small brain. Children have a slightly small size compared to adults. Men have larger brains than females.

Does the size of the brain matter really? Do they improve ones IQ?

Brain size tends to vary according to body size. The relationship is not proportional, though: the brain-to-body mass into varies. The largest ratio found is in the shrew. Averaging brain weight across all orders of mammals, it follows a power law, with an exponent of about 0.75.

So as we have people with big brains we have others with small brains? This may affect how we think

It depends on what body type and shape you have. If you have a giant body then ofcourse your brain size is bigger than the one who doesn't have  giant body. Similarly, the brain size doesn't effect intelligence.

Well to my understanding I doubt if the size of our brains really Matters reason been that God created us in a unique and wonderful way but it is one creator so you in essence our brain size don't determine our knowledge.
