I am very glad that at age 81 you have come to the same conclusion billions of people have arrived at already. Welcome!!!
P.S. Check my tagline!
...Look around - there are countless unmistakable hints that God exists...
Exactly. It does not take much to see if you want to see.
Look at flowers. Accident would have created bland, simple designs. You see the work of One who chose to display beauty, color, uniqueness for survivability. Almost like an artist creating gifts of love to a world he created.
Look at the birds, insects, small animals - each unique and specific for their needs. Accident would have created only a few with very basic needs.
Look in the eyes of dogs and family pets. Why would they have been made by accident? But, from a God who saw the need of something that accepted man as he was, that provided comfort, joy, companionship and love, it can be seen as a wonderful gift from a loving God. Accident would not have cared.
Just look at any aspect of life around you and compare what accident would have provided - something simple, bland, with few variations. But what do you see - each totally created for its purpose, with millions of variations of design with each for a purpose for that creature.
Again - the work of an Artist who loves the world.
