Saying there is a first Cause, a Source of life is not a cop-out. Eventually, we must go to a Source. We can examine what is created, what is here in front of our eyes, to determine whether we should believe in a Creator. The Bible reasons from effect to cause this way:"Because what may be known about God is manifest among them, for God made it manifest to them. For his invisible qualities are clearly seen from the world's creation onward, because they are perceived by the things made, even his eternal power and godship, so that they [persons who deny God] are inexcusable." (Romans 1:19,20)
You state that it is my opinion and not a fact that complex things can not originate without a maker. That is simply not true. Any entity that displays intelligent design (such as a bottle with a message in it) begs a designer. A person claiming a house built itself would be regarded as either crazy or lying. Yet, evolutionists ask us to suspend our common sense and believe that vastly more complex things (such as the cell) arose by 'natural law' or "natural selection". And not only that. That once the process started, we are to believe all the remarkably designed plants and animals and insects and birds that fill the earth were molded into existence by random mutations and 'natural selection'.
It is up to each person to examine the evidence, (not be swayed by the views of others), and make up their mind what the evidence proves.
