So, I was visiting the science museum with my daughter who is really, really into outer space science. She also has mild ADHD which always makes things exciting. Well, we met a female scientist there who talked to my daughter for almost an hour. Afterwards, my daughter told me to ask her out because she wants "her as [her] mommy forever". My daughter actually got her phone number and said she'd told the woman I was going to call her.

My daughter loves her so much, but this woman is extremely intimidating to me. She is way, way out of my league - to an extreme degree. I never even speak to women half as gorgeous as she is and I have never met a woman who is as intelligent as she is. I am an accountant, a single father, and my looks are average, at best.

What on earth do I do with this woman? I don't want to hurt my daughter and I also could never have dreamed of having a date with a woman like this.
I DO NOT want to fuck this up but I have no idea what I am doing. How do I impress this woman? Do I bring my daughter? What sort of date is good? Was this woman even serious or was she just being nice to my kid? There are so many ways this can go terribly...

I am totally clueless. Looking for help and advice all over the internet and I know you guys sometimes give ok advice soI thought I might cover all my bases... Thank you.
