A god can be anything you want it to be and more. You can not limit a god’s power just by thinking about it. This is what you do by claiming that gods are just life forms. A god can be a life form if you really need it to be, it can also not be a life form if that's what you require of it.
A god can walk right up to the boundaries of the real and the unreal and laugh at your efforts to tell which is which. Or it can sit patiently with you and help you figure things out. It can be the ultimate imaginary friend or it can be your cat. You decide what God is.
