Scientists teach us that there were certain factors that had to be precise to the decimal point in order for the world to be created. If it was slightly off then we wouldn't have a world.
If we look at our world today there are BILLIONS of things that if even one of them was different our lives would be unmanagable.
One example [please forgive me if you are put off by it]: Imagine we couldn't hold "it" in. It would just come out randomly whenever. Everywhere we would go there would be urine and feces. How unbearable would that be??
Another: Imagine there was no law of gravity?? Everything would all be flying all over the place!! It would be impossible.
One more: Imagine people would be born without hands??! Try going ONE HOUR without using your hands? 20 minutes!! Five minutes!!! We are using our hands ALL DAY EVERY DAY!!!
הודו לה' כי טוב כי לעולם חסדו!!
