In Nature: We have never observed non-living matter to spontaneously form life in nature.
In the Lab: The best scientists, labs, and universities in the world have never demonstrated they can create life from non-living matter even in a controlled lab environment. If intelligient designers (scientists) can't create life in carefully controlled lab conditions, is it reasonable to believe that non-intelligient processes can create life in a hostile natural environment, where repeatable science shows RNA and DNA degrade in long term exposure to water by hydrolysis?
Canned Goods: Every year the world produces about 80 billion cans of food. Canned goods contain proteins, amino acids, nutrients, and fragments of DNA. Yet life does not arise in them. This is experimental evidence that Louis Pastuer's Law of Abiogenesis is true - life does not come from non-life.
Speculation Evolutionists repeatedly use speculation. Speculation is not science. Examples:
