This tendency to see patterns even where none exist? Did man just decide to have this innate tendency for some strange reason? Why does man have this innate tendency to see patterns anyway?

Do you know of some connection between the two religion creating causes in humans?
Pattern recognition in humans.
To understand this, it is good to be able to understand human evolution.
Humans have evolved powerful mechanisms to understand sometimes complicated patterns. A simple example would be thus. Imagine a caveman who comes across two fruit trees. One bears many more flowers than the other. Later in the season, our blossom rich tree also bears many fruit. The following year our hypothetical man comes across two trees. One contains many blossoms, the other contains few. He can only protect one tree from others who would seek to eat the fruit. Which should he choose? If he makes the right choice, he gains alot of fruit, which he can use to grow big and strong, allowing him to attract many, high quality females. If he makes the wrong choice, he is not as strong, and either only has few children, or may even die.
The best theory for the large human brain that I have heard is of sexual selection. Females and males bring different things to the reproductive party. Males produce copious sperm (there are good reasons for this too), whilst females produce a single large egg, which they continue to feed for a minimum of 9 months after conception. On top of the energetic costs of this, females actually put themselves in greater risk by being preganant, they are less able to run away from danger, etc. So, females invest alot in reproduction. Males can essentially copulate and leave.
Over evolutionary time, females have exerted a pressure for fidelity amongst their males. When I say this, I mean traits have evolved within females that mean that most females will choose "true" males over "cheating" males. By having a mate which stays with them, they are protecting their own interests, a faithful male will feed the female, and their child. A faithful male will protect the female and their child. Indeed, this theory also explains the "seven year itch". By age 6, a child, whilst not independant by any means, requires a sufficiently small amount of a parents attention that a second child is likely to be successfully reared (of course, these arguments are more relevant to the human condition 10,000 years ago, rather than the highly artificial conditions nowadays, but they are still relevant).
Males are not exempt, and they have evolved mechanisms to fake being faithful. They look faithful, but really will further their evolutionary interest by fathering lots of childrem. This has set up an arms race, the net result being the development of the brain which, of course, is required to try and detect signs of deceipt in others. Look at how easy it is for clever people to decieve stupid people, for example.
This pattern recognition has been highly useful for us over evolutionary time, but sometimes works against us. This is the reason we have developed statistics for scientific usage, for example.
