Illustration of the probability to create building block of life by random blind chance without foresight and planning

A short 92 amino acids sequence to build a particular part needed for life has an estimated calculated chance of 10^63 according to a 1990 paper by two scientists from MIT.

Another scientist found the odds of scrambling 150 amino acids and getting any sort of useful protein has a calculated chance of 10^74. 

These propabilities are so small (impossible) that it is nearly imaginably impossible to understand and illustrate, but lets give it a chance.

Douglas Ell has in his book The God proofs: How science points to your creator made the following illustration by using cartoons to present the facts.

What is the reason why the naturalistic scientists still postulate that origin of life can be explained by a random blind process without planning and foresight?
