Why question the way the world has been created?

Why question the way the world has been created?/ Different lifespans

Why do we live for 50 to 80 years?  Why do human beings live for 70 years on an average when the lifespan of a mayfly is less than a day? A butterfly can live for a couple of weeks or a few months; dogs can live between 8 to 15 years - why is it that different animals have different lifespans?
 
I wonder about this sometimes and then realize that there is no point in thinking about this for that is how the creator has created it:  it is a design of the lord, of the creator, the master, the artist who has designed this beautiful world.  Now instead of questioning and wondering why this world has been created the way it is, is it not better to appreciate the beauty around us? Look at the flowers for instance - the artist must be truly amazing to have thought of so many colors and shapes, and created so many diverse flowers.  Look at the birds - the way they fly, the sounds they make, the music they create.  It really needs a very creative mind to have created all these birds. If you are still not convinced, then go under water and look at the colorful fish that swim in the corals. You will be amazed to find all that the creator of this universe has so beautifully created. Such art and artist should put our mind to rest, shouldn’t it?  Should we wonder and question why all this is the way it is?  Should we try to prove and scientifically understand everything or should we simply surrender, accept and enjoy this wonderful creation for the limited lifespan that we have?
