If I erase that origin, applying your condition extent(a) == extent(b) equals TRUE. The rasters still do not line up

You've still got a origin set in there. You can't do that. It will shift your rasters. If you have two rasters where extent(a) == extent(b) and they still don't line up on the plot, let me know.

This isn't much clearer. Load the source raster from file.tif into a thing called source and show summary(source). Then set up the raster with the target resolution and extent and call it target and show summary(target). Then do the reproject into something called dest and show summary(dest). Everything else is clutter.

The flip is because when I load the raster in R, is "flipped" like a mirror (up-side-down). Honestly, I do not know why this happens, but if saving it without the flip, the raster is badly stored. I have tried to set the origin via extent(test) but the problem remains, the resulting raster is a little bit up from the original. The original raster is file.tif = test. The purple is a polygon underneath, I did not turn off the shapefile.

What's with the "flip"? What is the extent and summary of your original raster? Why do you change the origin of r from the origin of test which it gets via extent(test)? In your image, which is "the original raster"? The one read from file.tif and called test? What's the purple?
