You have an explanation for evolution and adaptation to the environment. You don't have one for the information in DNA/RNA or how it came about
We do have an explanation, it is just that "evolution and adaptation" you talk about. The environment contains information. For example, the information that white things are difficult to see against a snowy background. Evolution adapts organisms to their environment, so a lot of organisms living near or above the snow line are white. That information has been
copied from the environment into the DNA of organisms living in that environment. Evolution is a copying process, it copies the available information into DNA. The copying process is not very efficient, but it does work. Natural selection picks the random mutations in DNA that best match the information in the environment. White fur survives better than light brown fur in snow. Light brown fur survives better than dark brown fur in snow. In some cases, where the environment is snowy in winter but not in summer, the animals change their coat colour. White in winter, which is then shed for a brown coat in summer. That is information about the seasons copied into DNA by evolution.
Evolution copies information from the environment into DNA. The information does not originate with evolution, but originates in the environment and is copied from there.
If you wish, your God created the universe -- the environment -- and evolution just copies the information placed in the universe into DNA. Genesis tells you that God did not create living organisms directly: "Let the waters bring forth..." and "Let the earth bring forth..."
while intelligence is always an option in anything that specified and complex and in fact should be the prime candidate.
Intelligent design is not an option for the first intelligent designer. That designer cannot have been intelligently designed, because it is the
first intelligent designer. There was no earlier intelligent designer.
The charge is that design is rejected in the design of life and is automatically rejected without cause.
We agree that science does not automatically reject design, and the LGM hypothesis shows.
If life is intelligently designed then, logically, you have a non-living intelligent designer. A living intelligent designer cannot originate life because it itself is already alive. There is a perfectly good logical cause for that rejection unless you can show the existence of a non-living intelligent designer.
