Ah, alright. You seem to have picked up quite a bit in the last year and a half.

Evolution is one of the simplest concepts in science to grasp, as it can be explained in a few sentences and requires no specialised knowledge, so I'm rather surprised, especially since it's in standard school curriculum. The term "survival of the fittest"/"natural selection", one of the core principles of evolution, is almost self-explanatory:
As you must know, children of the same parents, while not identical (unless they're twins), share many things in common with each other and their parents. Out of a group of individuals, those who are the most physically and mentally equipped to live in their environment are the ones who will have the highest chance of survival, and therefore have the highest chance of reproducing and passing off their better-equipped DNA. In due time, the survivors' DNA will be the only DNA remaining - the DNA of those less equipped will have been "naturally" weeded out (or "selected by nature"), as they were not capable of surviving en masse. Over long periods of time, this means that certain features will start to become pronounced and commonplace. Let's reshape this now regarding humans and their intelligence:
A group of apes go on an adventure, and they end up settling in colder, rainier location. The apes who were intelligent enough to realise they could use large leaves as umbrellas to shield against the cold rain were the ones most likely to survive long enough to reproduce. The group now only comprises rather intelligent apes. Their intelligence comes hand-in-hand with drive and curiosity, and they push forward further into the unknown, into an even colder climate.
While these apes may have been intelligent enough to use leaves as umbrellas, only the most intelligent of these apes were able to figure out how to stack sticks, branches, leaves and mud in order to create shelter from the cold wind and the rain. They reproduce, and push on further to the unknown.
New predators have appeared that their ape-like bodies were no longer equipped to deal with. While initially able to outrun the predators, many of the apes did not have the endurance to keep their speed up and were quickly killed off. As the apes did not stand a chance against the predators using traditional methods, only the most intelligent of these apes had figured out that rocks and sticks could be used as weapons. The apes with the longest legs and most powerful glutes/thighs (the recipe for bipedalism and endurance) - those able to escape their predators, and the apes who were intelligent enough to use weapons to defeat their predators, were the only ones to survive and reproduce.
These extremely intelligent apes chose to settle down for a while. While they were capable of beating their predators, it was no easy task. The more intelligent of these apes considered what kinds of sticks and rocks were most effective against the enemy - clearly, the pointy ones. They discovered they were able to grind rocks together to create sharper rocks, able to kill their predators in a single stab. These are the apes that survived to reproduce in the greatest numbers, and pushed on further into the unknown.
As intuition and thinking power has become central to these apes' ability to survive, the apes less capable of thinking straight were more likely to get killed off. The primary cause of this was brain fatigue caused by overheating, caused by an inability to sweat efficiently. The apes with the least amount of fur were the most adept at normalising their body heat, and were therefore able to utilise their minds to their fullest potentials, and were the ones who survived to reproduce in the greatest numbers.
After grinding so many rocks together, something special happens - a spark jumps out and fire is born. It became clear to the most intelligent of these uber-intelligent apes that fire, when harnessed, could be used as not only a weapon, but as a light and as a heat source, enabling them to easily fend off predators they once feared and brave even colder climates. Having been used to sheltering themselves for so long, it came as no surprise that light, portable shelters, or "clothes" could be constructed.
Time continues to pass, and of each group of apes, the most intelligent are always discovering something new to make surviving easier, and of those intelligent apes, the most physically adept end up being the ones most likely ones to reproduce.
Here we already have apes intelligent enough to clothe themselves, construct villages with fire lights and fight with weapons. They've lost their fur, and have begun walking on two legs. Sounds rather human, doesn't it? Remember that none of this happened as quickly as it sounds; a single one of the aforementioned stages would've taken tens of thousands of years of gradual adaption to fully complete. Also, like said, this isn't the only relevant component to evolution, there is a random element as well: mutation. While mutations generally have a negative impact, they can, on occasion, provide someone with such a strong advantage that it essentially ensures their survival, and this new mutated version of the species becomes the norm. Mutations have been the root cause for some very prominent parts of our evolution. While statistically beyond unlikely for an individual to hit a mutation like that, over the span of such a long period of time with so many beings, the idea of it not happening actually becomes statistically unlikely.
Again, all of these things are, for the most part,
entirely logical conclusions you can come to
simply knowing that children are different from their parents, but not too different. Perhaps not the exact progression of these things (this story and its progression weren't incredibly accurate, but it's not too far from the general idea).

this video, even if it won't change your opinion you might find it interesting (because evolution is actually really cool

). We didn't evolve from monkeys or gorillas, but gorillas and other apes including us did evolve from an earlier animal; it's not like a chain, it's like a tree, and all of the apes are at the ends of the ape branches.
I was actually about to draw a diagram, but I couldn't find my tablet pen, so I ended up telling a fun story instead.
