The extensive science supporting Evolution is readily available and has been reviewed and confirmed by tens of thousands of scientists.
It is up to Theland to show exactly where he claims it is wrong so we can debate the points.
BTW "you have been taken in by evolution hype" does not constitute a critique.

Theland //can you search the Internet and find just one example of one species changing into another?

You have not tried very hard then.
"The best-documented creations of new species in the laboratory were performed in the late 1980s. William R. Rice and George W. Salt bred Drosophila melanogaster fruit flies using a maze with three different choices of habitat such as light/dark and wet/dry. Each generation was placed into the maze, and the groups of flies that came out of two of the eight exits were set apart to breed with each other in their respective groups. After thirty-five generations, the two groups and their offspring were isolated reproductively because of their strong habitat preferences: they mated only within the areas they preferred, and so did not mate with flies that preferred the other areas.[58] The history of such attempts is described by Rice and Elen E. Hostert (1993).[59][60] Diane Dodd used a laboratory experiment to show how reproductive isolation can develop in Drosophila pseudoobscura fruit flies after several generations by placing them in different media, starch- and maltose-based media.[61]"

In this case without requiring humans to be involved.
"Critics of evolution often fall back on the maxim that no one has ever seen one species split into two. While that's clearly a straw man, because most speciation takes far longer than our lifespan to occur, it's also not true. We have seen species split, and we continue to see species diverging every day.
"For example, there were the two new species of American goatsbeards (or salsifies, genus Tragopogon) that sprung into existence in the past century. In the early 1900s, three species of these wildflowers - the western salsify (T. dubius), the meadow salsify (T. pratensis), and the oyster plant (T. porrifolius) - were introduced to the United States from Europe. As their populations expanded, the species interacted, often producing sterile hybrids. But by the 1950s, scientists realized that there were two new variations of goatsbeard growing. While they looked like hybrids, they weren't sterile. They were perfectly capable of reproducing with their own kind but not with any of the original three species - the classic definition of a new species."

Theland //But in spite of some changes, what began as a fly ended up as another fly.//
But the new fly was different species that could not breed with the original. Once they can no longer interbreed the two species are free to continue to diverge. That was in just 32 generations. How much change can happen in a million generations?

Let's cut to the real chase.
Humans and chimpanzees each have about 22,000 genes. About 99 percent of the genes we share are identical. Allowing for insertions and deletions, our genes about 96 percent the same as a chimp.
Four percent of 22,000 is less than one thousand genes. (Lets keep the maths simple.)
The last common ancestor of chimps and humans lived about five million years ago. Allowing for an average reproductive age of 20, that amounts to 250,000 generations on each side or 500,000 opportunities for human and chimp genes to diverge.
So a non-harmful change to one gene every 500 generations is all that would be required for chimps and humans to diverge from a common ancestor. Moreover, those changes can occur anywhere in the population and will spread throughout the population over a few generations if they are beneficial. So really these mutations only needed to turn up once in each several tens of thousands of matings to explain the divergence of chimps and humans from our last common ancestor.
Small change accumulate. Seventy percent of human genes are found in Acorn worms. Our ancestral lines diverged much further back.
We share many important genes with every living organism including bacteria. We all have a common ancestor going back about four billion years. All multicellular organisms diverged from a common ancestor between 1.5 and 2 billion years ago.

spath //Why do so many cultures all steaming from different places and situations all have this ideology that there is an all powerful being known as "god", //
Different cultures have very diverse mythological explanations for the origin of everything and its nature.
They are known as "god" only through translation of their locally used words. In some cultures the nature of them are so different they don't even get translated as "god". For example, the traditional culture of one of the old civilisations, the Australian Aboriginal people doesn't include the idea of gods.
