No. Atheism is the default setting until such time as substantiated evidence of the existence of deities is produced. Same applies to the many other products of human imagination such as unicorns, wizards, hobbits and elves. It is not “ignorance” to reject fantasy as real. OTOH: It is gullibility to accept it without credible evidence.
So...then your particular atheist position is not that it is the default setting a human being. It requires something which replaces ignorance with data of experience.
Within the context of that experience the focus is upon theism, all things theist. Such concepts are deemed surplus to the requirement of knowledge in relation to all things physical.
This is your position?
My position looks like an atheist one except that my focus is not upon theism and I also acknowledge that anything which comes or can be sourced to theism is not the last word on the subject.
Since that is my position, while I appear to be an atheist, I am not.
I have been mistaken by atheists as being an atheist because I am not a theist.
My default position in relation to yours is that the physical universe proves itself but does not prove its source or provide account of its existence one way or any other particular way.
Death is the certain advent which promotes subjective rule as more a priority over objective reality and is observed as a physical end, and depending on subjective bias can altogether be regarded as the end of the matter as far as the subject believes of their self.
Atheists apparently think so and theists say 'death is not the end' and 'run you fools!' and other such expressions.
Such things are actually unknown and by default should be seen as pointless to argue about from positions of belief and assumption one way or the other.
My position ensures that I do not block out possibilities but neither do I take them on as beliefs. I can think about the universe in the context of possible preexisting consciousness involved, and go where the fractal nature of such thinking processes led me.
All while remaining quite inside the reality of the physical universe.
And not at all interested in the possibility of invisible fairies, unicorns, spaghetti monsters or magical beings existing.
