Create an animation video

I run an education company that works primarily with university professors to produce interesting educational content for everyone. We are planning to turn some of our hypothetical discussions with professors into animated videos. The discussions include topics like "What if human beings had wings?" and "What would happen if we lived in the ocean?"

We are hoping to create animated videos that look like the following:
1. https://www.youtube.com/watch?v=lheapd7bgLA&ab_channel=Kurzgesagt%E2%80%93InaNutshell 2. https://www.youtube.com/watch?v=D9N7QaIOkG8&ab_channel=TED-Ed
3. https://www.youtube.com/watch?v=QKae1k1BDdA&ab_channel=TED-Ed

Our audience would be anyone on YouTube, from young children to adults, so there isn't a specific target group. Our team created a script and voice-over already for our first topic, "What would happen if there were no friction on Earth?"

Please share some of your prior animation video work and your thoughts. I'll share the video script and voiceover, and I look forward to working with you!
